1. Gas Stoichiometry
Molar volume can be used in stoichiometry calculations to convert quantities of chemicals in a chemical reaction.
This ONLY works if the reaction is at STP.
1 mole of gas = L of gas

2. MOLAR ROAD MAP
Moles A: Moles B
RATIO (using coefficients) A B

3. Ex1: How many liters of KClO3 must be decomposed to produce 10
Ex1: How many liters of KClO3 must be decomposed to produce 10.0 L of oxygen at STP? 2KClO3  3O2 + 2KCl
10.0 L O2
22.4 L KClO3
1 mol O2
2 mol KClO3
