The molarity formula is:
M = n / V
M is molarity
n is number of moles of solute
V is volume of the solution in liters
This equation may be rearranged to solve for any one of those three variables. The units of molarity are moles per liter, mol/L, or simply M, which is pronounced "molar."
In this video, I also describe how to make a solution of a certain molarity.

UA-cam should make a college and/or high school only using UA-cam teachers like this. Imagine how amazing it would be.
Try Khan Academy. Very helpful.
@@stickshiftstarship i pissed on the floor khan acadamy didn't help me
That won’t happen, they want us to be dumb
Really, most of the exams I wrote were from watching youtube videos. Very helpful
Iam here now because my teacher is showing us this as course material, so yes, definitely youtube is a college...lol
I just want to say thank you so much for reading everything out loud that you were showing on the screen. I am blind and this means so much to me. It helped me to follow along with exactly what you were doing. I’m actually a chemistry nerd, but I’ve always hated chemistry with numbers because it’s been difficult to visualize. Organic chemistry is more my style, but I needed this information to record a TikTok video, so thank you!
You cant see?
Oh wow, I understand it so much better than my Chemistry Teacher. Thank you this was extremely helpful. I wish teachers would put some passion in teaching to help students successful. I am currently a student at SCC. Thanks
You're welcome!
Super cool caschool
Agreed!
@@ketzbook sir can u explain aldehyde ketone and carboxylic acid
Me too
POV: your wathcing this the day befor your exam because you have no idea what chemstry even is.
2hrs before 😭
3 hrs before 😢
Why does your comment feel so trueeeee !!! Relatable 😢
Watching it on first day of my job yayyy
Tragic😢
I watched this video three times over and finally understood the concept, thanks to Ketzbook and my lovely chemistry teacher. Everything makes so much more sense, and I passed my chem test, thanks Ketzbook!
you are my hero 2019 (medical chemistry)
I have a lab practical tomorrow, and this video cleared up so much confusion. Thanks!!
When I started watching this I had no idea what molarity was at all because the teacher made it so complicated and literally not 3 minutes in I understand it to the point of solving the problem on my homework I had no clue how to do. Amazing video thank you
Glad it helped!
It took me 7 hours to figure that out on my own, this video explained it in 7 minutes lol
i was really confused by this topic and always lost my numbers but this helped me through the chapter easily . thanks a bunch !
OMG I LOVE YOU!!!!! I’ve looked at other UA-cam videos and didn’t understand but this helped me so MUCH.
I really hope you have an amazing year!!
i missed the class we learned this and i have a test on it tomorrow but this video explained it perfectly! thank you so much, you have most likely saved my grade :)
this video is the only reason my academic comeback actually worked. W video
glad to hear it helped!
Taking Clinical Chemistry and had some review problems like this. Only problem is I took Chem 2 YEARS ago for my first degree. This video explained it so much better than my lecture. Thank you!
you're welcome!
my teacher took 2 months this man took 2 minutes to make me understand
Good presentation that includes all the aspects that a student needs to know for a thorough understanding of molarity and concentration. I particularly like the variety of examples provided that demonstrated the different ways in which molarity could be use. the video is short but yet so enlightening. Good job!
Thanks!
Your way of presentation is awesome. Making complicated topics into easier. Thanks.
Expecting more topics from thermodynamics and complex compounds.
Really helpful ....one of easiest way of calculating molarity.... Basic concept is clear ....
Thanks for making this easy...
thank you human, currently crying over my homework but your video helped me
Thank you so much for this tutorial! I understand what my chemistry teacher says because he makes it sound complicated!!!!
Oh God! Was looking for such an easy and concise video on Molarity. Really relieved. My Chemistry teacher screwed it all up. Thank you so much....
you're welcome!
@@ketzbook CuS04×5H2O, on 6,50 second, why 9 O?
thanks for being simple and precise!
welcome!
I hope all chemistry teachers are the same as you. same for math teachers
Why don't I find this earlier?! I rely on crash course for these vids but it all was So hard...
Yours is like mind blowing! Thanks a lot for this!!!😊
Been looking for 5:32 kind of quewstion for a whole hour, now. Thank you, saviour.
This video was a little fast paced, but VERY helpful! Thank you : )
you are welcome!
@@ketzbook Hey Ketzbook, I have a question and couldn't find the answer to it anywhere on the internet or in my textbook, hoping you can answer it.
In these problems, how can something like an acid or a base have molarity? What is the solute and solution involved in calculating the molarity?
@@prxnv the acid or base is the solute. An acid or base will act the same way, more or less, as any other solute.
I'm literally a biochemical graduate and couldn't understand my values were totally whack. Then I watched your video and I LITERALLY WAS SOLVING FOR N INCORRECTLY. 😭😭 I've been using this equation for 7 years and all of a sudden, forgot how to math. Love the way you explained the very basic of everything! Keep up the good work!
For a second I thought your handwriting was literally soooo good and I was so confused at how you were writing so perfectly. And then the moment was shattered when I realized what was happening.
THANKS for explaining step by step
holy shit, i didn't realize my middle school teacher was teaching this complicated crap, thank you for simplifying this.
After a long struggle i learned molarity very well . thank u sir
you're welcome!
You are the best in teaching Chemistry in UA-cam, concise and right to the point, thank you and congratulations.
Roberto Pizano
thank you so much, more clear than my chemistry teacher..
wow it was such amazing lesson . thank u i understand now whereas in class i didnot
Great method, clear, practical... awesome!
Real
The best video 📹 I ever found on UA-cam.
Thank you very much 🙏.
Thank you so much your video soo easy so amasing and very informative
Thank you sir 🙏 it is very helpful in the last moment ☺️
Great video. Simple and succinct!
Thank you very much, saved my test results 😋
Thank you so much! I'm taking a test on Thursday and there are subjects on Chem and physics, and in High School I didn't take either. I regret it, but the classes were full so I was placed in Marine Biology:/
You're welcome, and good luck!
NIce explanation! I`ve done them all correctly the first attempt (I accounted for 159.609g/mol as the molecular mass of CuSO4 as this is given when you look it up. However, the method was right and then I did it again with your 249.7g/mol). I got them all right:) - it`s simple, when you know-how.
Same here. I wonder why the huge discrepancy between molar masses depending on where you look them up.
Thank you so much for this. I'm in a nursing prereq track and have been continuously struggling with general chemistry.
The only part that really confused me was the solving V=n/M because you converted the L to mL and I was confused as to why.
I hope that I will be able to find your vids for the rest of the topics throughout the rest of my semester!
THank you for sharing your knowlegde may God bless you sir
you're welcome!
Hey tanziro from demon slayer
Amazing explanation 🥰🥰
This is actually perfect, very understandable
You are an iconic teacher
😉
I love your videos so so much
This one is so helpful cause I am to write an exam tomorrow
I wish I could understand my teacher like this
Thanks for your help Sir you helped me to understand it in a easy way
THANK YOU, you sweet angel of Molarity!
Ohhhhh u're so great thanks for everything😊😊😊 may god bless you!!!!
You are so welcome
Thank you for this video!!!
I take Chemistry online, and the book is so confusing. I wish the book/online program was a clear as this. Doesn't make sense to pay nearly $200 for a digital book, then have to look to the Internet & UA-cam for answers...
Fantastic! your explanation is perfect I understand it better thanks
The video is really so helpful!! Thanks a lot!!
you're welcome!
professional and simple
thanks
you're welcome!
Thank you this video is very helpful for me 😊😊
Thanks this was really helpful on my chemistry 181 homework.
i understand it much better than my chemistry teacher
Sir I am form India I can not understand mority in my class then I watch your video understand mority easy way thanks so much
Bhai main bhi Bhartiya hun
R.I.P english
Well explained....thank you sir
Very helpful! Thank you!
Best tutor ever.
Omg I actually love u so much! Thanks for this!
You're welcome!
so clear, great educational tool!!
this is super cool... Thank you so much
Wow u r number one teacher😍
You are amazing. I think I understand now.
I'm so confused V shouldn't be nxM? Instead of n/m??? Why you didn't use the original formula in that case which is M=n/v ???? Why did you decide that n= M.V is the closer formula to V= n/m when M= n/v is just as close? this doesn't make sense to me why?
Gratsy this is awesome i think am in love with chemistry for once
great to hear :)
@@ketzbook yap thanks alot to you guys you really help alot continue with tha gud work God bless
thank you homie that helped a lot the other videos from my teacher sucked but your pretty lit bro
:)
Excellent presentation very easy to understand sir thank you for your hard work t make easy to understand
you're welcome!
You are absolutely genius
explained very well. thanks!
Well explained , thanks
I understand a whole semester with a few yourube vidoes
Nice information sir ji
Excellent practicing I needed to review mire samples...
Thank you sooooo much great explanation 👍👏🥰🥰
you're welcome!
Man this helped so much, Teacher is a good teacher just was having tons of trouble with this topic.
Thank you so much, I really appreciate your help
thank you very much for making video on "molarity" please make on video on "NORMALITY"!!!
Yeah!!
Same here pls
Ya, we want normality
helped a lot!
great :)
Agreed !!!
When a guy on the Internet is a better teacher than your actual 'teachers' at school
extremely helpful!!!
You. Are . Awesome.
I think a very helpful addition to this video would be how to make a solution of a given molarity if your solute is also a liquid instead of a dissolvable solid
Helped me when my honours supervisor didnt want to haha Thank you!
Thank you, double thumbs up 👍👍
you're welcome!
7yr ago is amzing but i love the content
Thank you Sir
Amazing lacchar
Really amazing .its help full
Sir made a lecture on molality plzz
I want to make liquid glass. I need to know about moles to do it - Oh, how I wish I hadn't hated doing the maths when my brain was younger! I'm more clued-up than I was before watching this video but I know I'll have to watch a few more before I'm in any way confident. Baby steps for me, I think. This video is a little over my head ... whoosh! And thanks.
thank you so much bro... its really work for me .
really does help with resub revision
great work sir
marvellous video
now i can do such type of questions
thanx a lot
good to hear!
This really helped 🙇♀️🙇♀️🙇♀️
Wow!!! our teacher was explaining in such a complicated way that I thought this thing was very difficult but now after this video, this thing is very easy. Thank you‼️
Glad it helped!
Best Video I have seen!
i had to convert everything from ml and litres to cm^3 and dm^3 because i live in the uk but the video was really helpful.
