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).

    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
