## Stoichiometry: Chemistry for Massive Creatures—Crash Course Chemistry #6

Chemists need stoichiometry to make the scale of chemistry more understandable—Hank is here to explain why, and to teach us how to use it (13 minutes). A YouTube element has been excluded from this version of the text. You can view it online here: http://pb.libretexts.org/gcll/?p=128

## Stoichiometry Problems: Moles to Moles

Shows how to use stoichiometry to determine the number of moles of reactants and products if you are given the number of moles of one of the substances in the reaction (5 minutes).
