How to Find the Mole Ratio to Solve Stoichiometry Problems
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).

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...

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 ?

Glad it helped! It's a tough concept. This might be useful as well: breslyn.org/chemistry/stoich/
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?
KEEP DOING YOU! YOU ARE AMAZINGGGGGGGGGGGGGGGGGG!!!

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

Can you please do using grams
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.
My chemistry teacher managed to overcomplicate the mole ratio. It was simple as DOG all along
