Module 8--Stoichiometry
_____'s Law states that the stoichiometric coefficients in a chemical equation relate the volumes of gases in the equation as well as the number of moles of substances in the equation.
Gay-Lussac
Stoichiometry can only be done in moles. So, the first thing you must do is _____ to moles. (Unless you're comparing gasses. Then compare their volumes.)
convert
A chemical formula that tells you a simple, whole-number ratio for the atoms in a molecule is a(n) _____ formula.
empirical
Gay-Lussac's Law can be used in stoichiometry only if everything you are using in the problem is a _____.
gas
