The word "mole" suggests a small, furry burrowing animal to many. But in this lesson, we look at the concept of the mole in chemistry. Learn the incredible magnitude of the mole--and how something so big can help us calculate the tiniest particles in the world.
Lesson by Daniel Dulek, animation by Augenblick Studios.

Every time he says "unfortunately", it sounds like "fortunately". Threw me off!
Fortunately Avogadro died in 1856
Big difference between fortunately and unfortunately I wish he’d speak clearly
Nope, sounds legit like fortunately
Did he even said unfortunately?
Ok
The penny analogy literally blew my mind!
Honestly! I also laughed at the baby lol
Funny thing is, he stole the concept from someone.

Saili Liao It's word for word the same.
No way it's just a coincidence.
Vayne Hellsing There's still a chance, albeit a tiny one
He was my high-school AP Chemistry professor! I know of very few chemistry professors who could only begin to rival his passion for, and knowledge of, the subject. I'm a Biochemistry and Molecular Biology major in college now because of him. Thank you, Mr. Dulek!
wow awesome
I thought u were talking about Lorenzo Romano Amedeo Carlo Avogadro at first

That’s wonderful! A great master makes a great student. Thus the cycle renews
Why do people finally like a persons work after they’re dead
FISHY EVERYTHING their not liking them because there dead. They're do you get it?
RIP English
"Why do people finally like a person's work after they are dead?" Please, do not rage, I corrected you simply because I learnt English in UA-cam this very way :)
But Why 6.02 * 10^23 and not 602 * 10^21?
that's the standard form of writing extremely large or small numbers
I wanna be a moleionaire.... XD
LearningLife lol
I want Grahams number in milipennies
I'd be happy with Avogadro's number of millipennies. But they'd have to be notional, rather than actual, because storage would be a huge problem.
Not so fast
If you had a mole worth of money, the amount of money in circulation would multiply by a couple orders of magnitude and would cause some extreme hyperinflation so your money would be worthless
Who doesn't
I need a mole of money...
Ok, I'll give you a mole of Hungarian Pengö, which, according to this: www.globalfinancialdata.com/gfdblog/?p=2382 (and assuming I'm doing the math correctly) was worth just over one tenth of one US cent in July 1946.
Adam Weishaupt still very worthy it!!! How do you want to transfer the money?
Someone copied this 4 year old comment 2 years ago
You, a Russian?
Adam Weishaupt so what you are telling me that if I time traveled to 1946 and gave a Hungarian 5 dollars their economy would crash due to inflation
This is such a good explanation. I’m doing HSC chemistry and one of the things I revisited was the definition of a mole. My prof is usually well versed on practically anything but when I asked him this there was a surprising doubt. Not because he didn’t know of course, but it was hard to translate to words. This does that beautifully
Feel sad for Avogadro!

Saili Liao whatever

Sad is also ok tho.
It still makes sense

Just Enough!!! for diabetes. It can give diabetes to a whole country twice!!! or even more!!!
other than the analogies and learnings i really love the animation. you guys never disappoint with the animation so thank you !
I feel it's relevant to mention that the reason the mole is so important is because it's the conversion factor between amu (the mass number on the periodic table) and grams. That's why a mol of water weighs 18.01 grams and a single molecule of water is 18.01 amu
Im going to pretend i understand. 😭😭😭😭
This is the type of stuff that came out of the mouth of my chemistry teacher which made it completely impossible to grasp.
@@Joel-zo6yo -
I just show my kids
(12 amu in grams)(mole)=12grams
Solve for mole and you will get avogadro.

Do you make the “slower” students stand at the chalkboard/whiteboard and try to work out equations?
A balloon at 0deg C and a pressure of 1 atm has 6x10^23 gas particles - nope - only if the volume is 22.7 L
nope, it is 22,41 l
Lectiuss ur right it's 22.414 l in
1atm and 22.7 in I bar pressure.Now the latter is the stp.
You can change the volume without changing its temperature or pressure
Koha Raisevo but then you are changing the quantity of particles which is the whole point
A slight correction: volume at STP=22.4 l

3:17 who read that wrong just like me?
Me to 😝
How
What?
a mole of penises?
Me 😂😂
I like the way the represented a very hard to understand concept thing in a humourous way, just to makr the the video exiting and less boring. Keep it up guys! Your channel is very unique like our earth
U should have explained mole concept a little more.Like,why 18.01 ml of water is one mole?
the mole is defined so that one mole of hydrogen atoms (which weight 1u, atom mass unit) has a mass of 1 gram. Water has one oxygen atom (16u) and two hydrogen atoms (2u total) which adds up to 18u.
Is that mean that 18ml has 6.02*10^23 but how to have 1 molecule of water then how much does it weight?
Ahmed Mohamed 18/6x10^23 gram. Which equals 3x10^-23 gram
RAGHURAM .R thank you but how will it be its voulme and what about one drop of water is all matters have the same voulme of 1 mole ?
cuz the atomic weight of water is 18.01 lol
Dude, thank you. I was having trouble trying to explain a mol for a Chemistry lab. Much appreciated!
Immortal Blazer mol is the correct abbreviation for mole

@@nicksabahi6551 mol is the shortened version of mole. Chemists will do anything to shorten a word, even if it means only dropping 1 letter
i can explain it better
I loved your explanation 👏👏👏i like simple and quick information, it completely entrenched in my mind
Actually his full name is
Lorenzo Romano Amedeo Carlo Avogadro di Quareqa edi Carreta😌😌
NCERT?
Ohhhhhhh myyyy goood
The penny example BLEW MY MIND. wow
Very good and funny and informative at the same time! Excellent narrator!
whos watching this in chemistry.
Same here
Same but do you think we can find moles in food??!
Like I’m doing a project I need to know how tall is a mole of tacos? Is that possible to find ?
I need help 🏃🏻♀️

a great presentation
really useful for students to get the idea ... comparing it to other simpler examples

My teacher showed us this video it really helps. thank you ted-ed.
I really lov the animations of this video and I took away more than just the mole!
Hey Ted, can we have our baby back? Thanks - everyone on WSB
This didn't explain it very well. A mole is the amount of atoms in twelve grams of carbon twelve. in other words it is the number of atoms required for something to weigh as much as its molecular or atomic mass.
Najey Rifai that is for molar mass
Nope, that info helps understanding better. One might wonder where the Avogadro's number comes from. It is the conversion factor between grams and atomic mass unit.
The two explanations reach the same end point, one of them is purely scientific which is hard for people just starting chemistry to understand, and then there are the ones in the video
Yes but people new to chemistry won't understand it, that defiant ion won't help person understand a mole is it would rather confuse them
Yeah, I actually learnt that definition at school. But there is a problem though. We will then have to prove that Avogadro for every element is the same number!
Just learned about this in school and was a little fuzzy about it. This cleared it right up! Thanks!
Now this is one of my favorite ted ed vids.
i don't see mark and expiry
Thank you for this video, I can still remember my High School Teacher yelling at because I didn't comprehend the concept of a mole. Here's to you Mr. Nagasaki.
Thaaannkk you!! The animations made it easier to understand 😄
This is the most interesting presentation which was so funny. I loved the humor flying through this video🤣🤣
Strange in chemistry class we call it a mol , without the e
+TheMonyarm mol is the SI abbreviation for the unit, while mole is the English name.
"Mol" is the unit abbreviation of mole, just like "m" stands for "meter" and "g" stands for "gram".
it's actually the symbol for it's unit.... "Mole" is the unit and "mol" is the symbol for the unit.... just like kg for kilogram
3:19Thats the WallStreetBets logo!
Thank you sooo much! I was going to suggest this, being that it is a complicated concept.
the animation is just brilliant!
1:04 The moment when I was giving my revision report to my laboratory assistant
He didn't mention about the relationship between the mole and the atomic weight. For those who couldn't understand why it's 6.02*10^23, let me tell you. Chemists made a so-called atomic weight. They decided that the atomic weight of a single Carbon atom, which has 6 protons and 6 neutrons, would be '12', and the rest of the atoms' weight would be decided by the relative weight of the Carbon. The atomic weight is pretty neat; almost every atom has a integer weight except a few (of course they are not perfect integers. They are very close to the integers, like 26.982; the atomic weight of the aluminium). If you take 6.02*10^23 numbers of an atom, there will be exactly 'the atomic weight of the atom' grams of the atom. For example, If you take 32 grams of an Oxygen atom, which has 16 atomic weight, there will be 2*6.02*10^23 numbers (=2 moles) of the Oxygen atoms.
Thnx
Superb class it really helped me a lot
so well scripted and presented and animated, fantasticoooo!!!
Who is the animator .. he/she is toooooooooo good in their field like tht coffee planet or the aunts mole ... SUPERB
Qaima Ali Animation by Augenblick Studios (It is in the description)
ikr!!! the ted ed animators are like crazyyy good!!!1
I love this animation! My favorites are the recurring mole and Avagadro's sideburns. I wish I had a mole of pennies!
Nice video. Thanks. Just subscribed. Wish this guy could be our chemistry teacher
I always write the same thing;
Your endings are loveable.
I suggest to make a lesson about the "PH level"
Congratulations on confusing me about something I already understood quite intricately.
Same
Savage😂😂😂
It explains it pretty well
Same :'(
Same... they confused me by showing so many cartoons and also the mole(animal one)
thanks! your vid really helps me teaching mole concept
2:21 Love the mole chilling out! 🥤
Avogadro's character design looks like it was from The Critic.
A ream of paper is actually anywhere between about 475 and 510 sheets. They do it by weight, which can vary in different runs. (might be by thickness, but same problem)
And yes, the average is intentionally a little below 500.
this is my favorite ted ed
I loved how Daniel Dulek narrated this episode. take love
I knew the ream of paper was 500
Andromeda Gaming I’m so proud
Me too
Good for you
wow!!!!! nice explanation why dont our teachers give us same explanation
I learn this in chem yesterday, n it really helped thanks a lot!!!!
This video was AMAZING!
You are here for 3:19
its a very good DD
CHANGE THE LOGO BACK WSB.
Thank you, you made an awesome video :)
so good.......... I just got mesmerized by the video........easy explanation and better understanding
Man if only I could picture a mole
"If you had a mole of donuts it would cover the Earth to a depth of 8 km"
Ah yes, I can definitely picture the Earth covered in donuts to a depth of 8 km.
well it certainly aint a video that would bore you entirely LOL
Finally, I can understand moles!!
Love this video! It is great!
moles grow to 4.4 to 6.25 inches (11.3 to15.9 centimeters) long from snout to rump. Their tails add 1 to 1.6 inches(2.5 to 4 cm) of length
They also grow up to 6.02x10^23
nuh uh@@kneelingfish437
WSB has brought us all together over here. SPY 7/17 180p
the mole puns transcended my existence beyond the realm of the living, thank you ted ed.
This animation was amazing
My my my, I laughed the whole time...man, what an awesome sense of humour...
It’s dark humor he never signed autographs course they never accepted him when he was alive
IV crushed :,(
Excelente video. Muchas gracias por compartirlo.
I wish my teachers of the difficult subjects in high school could have made learning fun and interesting like this.
I never could understand the concept of a mole or Avagadro’s (sp?) number. I dropped chemistry because the teacher couldn’t explain it below the level of the smartest five students in the class and the textbook was worthless. I wanted to understand it so badly but I just couldn’t get it.
On a lark, I was thinking about that today and decided to look it up. Forty-two years later, it finally makes sense to me, because it was simply explained. Thank you, TEDEd!
3:25 inflation?
3:16 who else mistook pennies for something else on the first read?
Me lmao
yeah i mistook that for pennies in currency, now i know what it meant, thanks.
One of the best and explanation ever
Watching it 7 years after I marvel at your work)
Misleading title: I thought you meant the ones on your skin.
that’s your fault sir
No mention of the whole, 'as many units, (molecules, atoms, etc.), as there are Carbon atoms in 12 grams of Carbon 12'? Or Oxygen atoms in 16 grams of Oxygen?
Great presentation..! Thanks
hey great vid dude. keep it up. you da boss.
who else is here just bc of school
Me lol
WallStreetBets sent me here..
Muy buen video, explicando a detalle y mencionando al que descubrió las bases de la teoría atómica en cuanto al estudio de los compuestos orgánicos, saludos
Your narrations have come a long way.
TIL thanks wsb
It could have been more useful if you explained how they came up with the avogadro's number.
thanks! I liked your titlle and the animation at the beginning too!
Pretty nice animation Augenblick Studios :D
2:09 still laughing 🤣🤣
You're the first person I've seen on UA-cam with the same first name as me.
1.000.000 $ every second for 100 years...and you still didnt spend even a percent of a percent...just let that sink in for a second
Animation style fits very well.
nice job Mr. full. tnx.
Funny and educative.. Like all my teachers, not
not, and who else? edit nevermind i get it
You need a sense of humor if u think that was funny
My teachers always explain it in such a bizzare manner telling us that it is just a unit of measuring matter's quantity 😒🙄😬 feels like my teacher also got her mind blown when she knew the penny's analogue 😒🙄🙄
@J You should have looked it up
