- In this video you'll learn to find the mole ratio from the coefficients in a balanced chemical equation. We'll look at several simple ways to find the mole ratio to build your understanding and stoichiometry skills. The mole ratio is a key component of solving reaction stoichiometry problems.
Note: the mole ratio is sometimes called the "stoichiometric ratio."

Converting between moles and grams is the cornerstone of being successful in stoichiometry, the study of chemical quantities. Take the time to learn mole conversions and you will find chemistry is much easier.
The use of conversion factors (also called factor-label method or dimensional analysis) is a more general technique for converting quantities. Once you understand how it works it can be applied to many different conversion (as long as you know the conversion factor).

This guy taught me more than my chemist teacher. I owe you my grades sir Breslyn! Kudos to you!
He didn’t teach you how to spell?
@@coleroberts4941 Apparently not haha. Forgive me, English is not my first language.
No man I was just joking not trying to be rude sorry if it came off as rude!
@@coleroberts4941 nah it didn't. I always welcome criticism when it comes to my grammar or spelling. so, thanks a lot man!
Not guy this is your teacher
you're literally my new chemistry best friend
Awesome!
Thanks
Omigosh!! I can't believe it... I did all that on my own just by seeing you do the first one. Thanks a lot!! You are a million, no even more, times better than my school teachers!!
I thought up of me as an idiot. But turns out that I just needed someone to explain it differently...
Good to hear! This mole stuff is difficult for everyone at first.
Here's my playlist for the mole and stoichiometry if you need help in the future:

omigosh!
@@wbreslyn sir u are a gift from god to as 🥹
at 2:39, why is the mol for H2O is same for H2 ? if H2 plus with O2 why won't the mol of H2O increase ?
Wow, i was struggling with this stuff. Thnx alot
Glad it helped!
Much gratitude. i have a test tomorrow and had no idea how this worked thank you so much the explanation was clear and easy to understand
All the best on your test!
Very clear and easy to follow and understand!
Thank you very much! Im usually pretty quick to learning Chemistry but these Mole equations got me racking my brain!
Yeah, mole ratios, and stoichiometry in general, are one of the tougher concepts for students. Glad the video helped!
Thank you for the great video! It really helped me!!
Thank you so much for sharing the ratio with fractions so much easier to understand than the teacher preferred way!
No problem, glad I could help with the Mole Ratio! --- Dr. B
Oh Thanks !
You cleared my concept in just minutes . Huge respect for you ❤ bcz you made this topic exceptionally easy for me .
Happy to help!
learned more in this video then a week of chemistry thank you
Happy to help!
Thank you, great explanation
Bro thanks I really feel enjoyed and relieved😊
Thanks, very helpful.
Wow this video explains it wayyy better than how my chemistry teacher does. Thank you so much
thank you so much that was helpful
thank you this was so easy to understand, you literally taught me more than my chemist teacher could ever.
Happy to help!
Amaizing ❤🎉
Thankyou soo much Sir.You explained it in a very excellent way
Glad I could help with the Mole Ratio! --- Dr. B
Even 4 years after the fact. Your video still helped me.
banger video. teaching so smoothly.
Bang bang
Excellent video! Thank you!
You are welcome!
You are a gem!! Thank you
You're welcome! Hey, you might find my new (free) video guide on stoichiometry useful too:
www.Breslyn.org
this has been fun omg
KEEP DOING YOU! YOU ARE AMAZINGGGGGGGGGGGGGGGGGG!!!
HOLY MOLY. Thank you Sir, I understand this topic so much better now and its way easier than what my teacher taught me. I have my Chem Exam tomorrow so this is a big help.
Hope your exam goes/went well!
thanks for being my go to for chemistry help wayne
You're welcome!
Thank you. Thank you. Thank you!! Seriously!!
Glad I could help!
--- Dr. B
You're a savior 💚
Thank you so much sir
You are most welcome!
Thanks for the guide. After a days worth of notes I still didn't really have the concept down(and I'm normally really good at learning quick in Chemistry) but this helped a lot.
Glad it helped! It's a tough concept. This might be useful as well:

Thank you so much.
You're welcome!
Thanks a lot you're much better than my teacher
You're welcome 😊
Thanks so much, I did this a few years ago in school and could not remember how to do it all when recapping for uni, this explained it so well. Thanks!
Thanks bestie!
That helped me a lot💕💕
Excellent!
Thanks❤️
so if its 2:4 you just times it by 2 and if its a lower ration like 4:2 you just times times it by 4/2?
I don't have the words to thank you ❤
My pleasure 😊
you have been helping me so much the past three hours. i also prefer doing cross multiplication since its way easier than conversion factor. Thanks again! :D
Glad I can help!
you just helped me get an A on my test
I love you fr ty
Thank you thank you thank you...
Welcome!
THANK YOU
Welcome!
That's good video it help me so much but my challenge are change the word equastion to chemical equastion i mean how to react it
omg mr thank you a loooooot 🥹💜
Bro make a video on volume to mass conversion
You explains this better than my profesor
Glad I can help!
I never can forget you.🙏🙏🙏🙏🙏
Thank you!
Ty so much , but how do I know what the question is asking for , I get a little confused on what to find out
Yes, that is often a problem for students. Typically they ask you to find grams. liters (volume), moles, or molecules. But for the ratio to work you have to be in moles. I just put up a section on stoichiometry over on my website you might find useful. Lots of practice with video solutions. www.Breslyn.org
Do you have a website with question papers? ❤
Here's my website! www.Breslyn.org Please share with others that might find it helpful!
thanks
You're welcome!
Can you please do using grams
I need help
For small numbers I'm using ( Parenthesis)
How does H(2)/O(2) have 2/1 ratio when they both have a (2) after it. Can someone please help?
You need to look at the coefficients, the numbers in front of H2 and O2. Ignore the subscripts!
@wbreslyn Thankyou so so much. Literally the only thing I can say. Thankyou
OMG THANK U SMM!! I GOT THE HANG OF IT:D
My chemistry teacher managed to overcomplicate the mole ratio. It was simple as DOG all along
shoutout to wayne. my gang member.
What is the mole ratio of 2H2 to 2H2O?
This should help: th-cam.com/video/pABeHtosDNs/w-d-xo.html
that whole equation that teachers give just deviates me and makes this subject so confusing, for 7:12 we werent given any coefficients, we are solving for it.
Sir one request plz take some of the hard questions asked in JEE
I'll try!
@@wbreslyn Sir and POAC and yield concepts also
Sir can u teach physics....?
Because sir ur explanation is very helpul...
Thanks! I'm concentrating more on chemistry right now since that is my background but I do enjoy physics and there is much overlap between chem and physics. --- Dr. B
@@wbreslyn okk sir no problem...!
GYATTT DAMMM MOLECULES
I’m so confused 😭
This stuff is really tough for most students, hang in there! It might be helpful to work through this website to make sure you get the key elements.

Note: converting between moles and grams is one essential element!
i think i have just been saved
my guy
No lentiendo teodio
ياليته كان بالعربي
How does no one comment about the dog lol
I've been wondering that myself!
