dude, this guy is the reason I have an A in chem. I truly could not appreciate him more. He teaches 10x better then my teacher no question. At this point I dont even need her lessons. He will teach me so much better.
Dude, ur an AWESOME Chem tutor!!!!
A mole's worth of applause to u 👏

Just started Chem again after 5 years and your videos are definitely helping. Thanks for taking the time to do these!
same!
my mind is just absolutely blown at how easy this topic is compared to how my shitty textbook spends 2 pages on it. god fuckin bless this account
you teach more than my highschool chem teacher oh my gosh idk what i would do w/o this channel
Bro I swear I saw your user in another comment section on chem videos 💀

this man using calculator, that's illegal.
@@a.pal_yt2018 😂
Dude, you're better than my school teachers! 👏👏
You're voice sounds so sleepy but thank you for that voice I learned this lesson. More power and God bless
It was truly amazing learning it with you
The way you explained it is so spectacular
Thank you for this video, I could not for the life of me understand what this was through the textbook, even with an example. Much appreciations
This is way better than my chemistry teacher.
You are a blessing to our time.
English isnt my native language but your video helped me a lot, thank you so much
300 dollar textbook: “explains it on the most complicated way to make it seem as if it was worth what they made you pay for it”
UA-cam video: Just do this, look for these numbers, divide them and you’ll be fine.
hi just a random doubt do you know why he multiply (*4) AT 6:46 ?
hoping for a reply.
@@rasneetkaur8363 to make it a whole number
😂😂
my god!! thanks wish me luck i've chemistry final exam nxt week!
This may be too late for you to see this comment since this is an older video, but THANK YOU for your explanation. I absolutely can relate to the way you explained this so much better. Much, much, MUCH appreciated.
I thought the definition of the whole number is all the number without fractions. In an example of NO, the ratios of A and C, and B and C do form fractions. I did not get why this example can explain the law of multiple proportion. Can anyone explain this one to me? Thank you so much. I am pretty sure I understood differently since I don't use English as my first language. Thank you guys!
Be June_주은 same i dont understand this law at all
Yea this doesn't make sense
he means that the ratio is a whole number ex.3:4 or 3/4 which are both obviously whole numbers, but when he puts it in fractional form, i see how that could be confusing
ohhhh
@@Mr.Opinion but that makes no sense every single ratio by that definition is a whole number - i mean there is no 3.75/4.23 ratio. I dnt get this
Professor Organic Chemistry Tutor, thank you for explaining the Law of Multiple Proportions in AP/General Chemistry. From watching the video, and doing problems, I still have some issues with this material from start to finish. This is an error free video/lecture on UA-cam TV with the Organic Chemistry Tutor.
After failing my Chen test today 😔, I supposed I’ll learn a thing or two and now I’m beginning to understand it even more
I’m truly great full 7:33
How do you know what numbers to use to multiply for the whole numbers?
Same, im stucked with that question ugh
@@martinastellaire This is super late but multiply the decimal by whatever number that's smallest that will yield a whole number. .5 is 1/2 so I need two halfs to make a whole. so .5 x 2 is 1. Or in the last example 11:06 the smallest number that makes 1.5 a whole number is 2, 1.5 x 2 is 3. Take that 2 and multiply it with the other compound so everything stays balanced.

i love the way he does it without showing his face or any body parts
You are an actual lifesaver thank you so much
This is the best channel ever
Hi. I just want to ask where did you get the 2 and the 4 for the multiple proportions?
He just came up with them, in order to make it a whole number:

Thanks bro u have no idea how u helped me 😀😄😀 thanks
Thanks you really helped me a lot❤
Nice teaching ...you have totally made to understand this
Whole number is a number without any fractional component then how is it possible that 5/4 & 5/2 are whole numbers rather than fractional numbers in the 2nd problem.
Yesss my same question today!
Think of them as ratios. 5/4 is 5:4 and 5/2 is 5:2. These are whole numbers when expressed as ratios.
Best chemistry Teacher
im in 8th grade learning this.. you are amazingg! my doubts are now clearr
Why learn this early
narayana?
Sir you are teaching nice
you are the best tutor 💙✨
Thank you for the explanation but I'm not sure I get it a 100%. Any fraction with decimals can be simplified to constitute whole numbers if you multiply it by multiples of 10. So does this mean there's no case to demonstrate the law is not obeyed?
You explained this the best. 😊 Thanks
How did you get 4 which you used to divide 1.25(C÷B)
same question here
This person really has a right to fund him due to his teaching procedure.
Alot of appreciation to him
Your question does not read that there are x2 100g of compounds. It reads that there is 100g of 2 different compounds, comprised of 50g of S and 40g of S. Please change the wording.
can somebody explain to me why he multiplied 2 and 4 to the over A thingy as well as the C over B...why 4 and 2?
Sorry for that, this dude is way better than my chemistry teacher.
Law of reciprocal proportion please
Thank you for your tutorials.
Thank you for this!!! I always understood the definition of the Law, but the stoichiometry calculations confused me. You cleared it up a lot!😁😁😁😁😁😁😁
You are really help me alot.
You are really awesome,and btw you have a really sweet and nice voice.😍😍😍
Hey. A in chemistry, I missed you
12:16 = 1:x X= 16x1/12. X= 16/12=1.33
thank uu smm! wala aq nagets sa module ko diko talaga alam gagawin kobkung wala tong channel na to huhu
Thank you very much !!! But I have one question here and i would be happy if anyone in the comment section give me answer for my question. The question is ; Does the ratio have to be larger:smaller for example, in the last example the result was 3:2 , Can't it be 2:3 and say A:B ? Which way is the correct way of writing? Thanks in Advance!!
both are correct
if its whole numbers, shouldnt it only be 0,1,2,3,4.... or am i wrong. 3/2 is a fraction right?
Just a question,how did you get what number is to be multiplied to the deciaml to get the whole number?
U jxt multiply it by the nearest number that can give u a whole number
Thank you! This helped me finally grasp the concept.
Short but informative
Night before from chemistry exam
Is it spelt SULPHUR or SULFUR. Or are they two different things
Please do a video and help me solve this question below.
an element form 4 oxides having percentage of X = 77.4 %,63.2%,69.6%,72.0%. VERIFY LAW OF MULTIPLE PROPORTION
For the example of oxygen and nitrogen, can we get the chemical formula if the compounds using only the data we were given?
When dividing stuff why r u sig figing it to 3 instead of 2 sig figs
Negative numbers, fractions, and decimals are not considered "whole numbers." A fraction is a whole number if and only if the numerator divides the denominator with no remainder ( which is a positive integer, not a decimal). As a result, such instances do not demonstrate the law of multiple proportions.
How is 5/4 a whole number??? I’m confused
Exactly. Even 5/2 is not a whole number, as far as I know www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-factors-and-multiples/whole-numbers-integers/a/whole-numbers-integers
Am sorry but why did you use sulphur for the first ratio can't we use oxygen first then our answer will be 2÷3 instead of 3÷2 I am confused pls reply early
where did you get the 2 & 4 you divided from, please?
Tnxxxxx teach😁😀 what a wonderful lesson
Thank you so much
at 2:31 i have a doubt 1 grams of carbon combine with 2.67 g of oxygen as according to law of definite proportions carbon combines with O2 in ratio of 3:8
how do u know what numbers to use to multiply to get the whole number? plz reply
thanks for making it easy
Thanks, that helps a lot!
is there a video about mixed equations and balancing them??
Thank you!!!!!!!!! Another great video.
Very helpful👏
BRO u r awesome💯
Hey, your great video gave me understanding about the topic, but where do you get the number 4 to be multiplied with 1.23 and 1 in 6:47 ?
If you would divide 5 and 4 you would get 1.25
That is why he multiply it w/ 4
Hi, I seriously love you.
Love you to
@@raymondchukwukelu336 LOVE YOU MORE
Great video, spoilt by getting the definition wrong; should have been “... a RATIO of small whole numbers.”
He makes complex concepts in chemistry easy.
Thank you so much ❤
Thank you
I loved it
i am subscribing u right noww!!
what is the point of this though. Like why do we need to show the relationship in whole numbers. For the law of definite proportions you could use the ratio between the individual elements and their corresponding compound to solve a problem taking to stoichiometry. however here it seems to just be about showing the relation between the two compounds such as an isotopic compound where the relationship is unclear.
Awesome examples and explanation! Thank you!
Please law of reciporcal proportions
Your handwriting has gotten neater. Thank you.
Thanks.... It was a great help😁
Which textbook do you use?
Does the last example problem correspond to any real compounds? If so, what is compound A ?
Compound A would be Sulphur Oxide, and compound B would make a thiosulphate ion, according to the respective stoichiometric coefficients😊
How is 2.5 a "small whole number"? Did I lose something?
i love the way he uses the calculator 😍
I'm confused. Aren't fractions not classified as whole numbers?
no
Made easy. Thanks a lot
Where did you pull 4/4 from??
howd you get the number that should be divided for getting the ratio
Hw do u get the four to multiple
Thanks 👍♥️✨
12 : 32 =1 : x. X = 32x1/12. X = 32/12=2.66
Bro thank you 🙏🏽
Thanks
at 0:55 shouldn't it be atomic weight, not atomic mass?
You're a good tutor but PLEASE SPEAK UP! I can barely hear you and have a hard time not falling asleep or understanding what you're saying. I had to put youtube up on the tv just to hear you
Can you tell me which software are you using in this vid ... Thanks in advance
