MOLAR VOLUME, IDEAL GAS LAW, GAS STOICHIOMETRY
CHAPTER TIPS . . .
KNOW LABELS!
mass (m) --> grams (g)
molar mass (MM) --> grams/mole (g/mol)
volume (V) --> liters (L)
molar volume --> liter/mole (L/mol)
Molar Volume of Any Gas = 22.414 L/mol at STP
density (d) --> grams/liter (g/L)
MOLAR VOLUME PROBLEMS
Solving for mass, moles, volume, density, molar mass (at STP, not at STP)
Not permitted to use PV = nRT
IDEAL GAS LAW
PV = nRT Solving for mass, moles, volume, density, molar mass
Beware of units!
R = 0.08206 L.atm/K.mol
GAS STOICHIOMETRY
At STP & Not At STP
May use combined gas law or PV=nRT when needed
Only use gas laws with gases!
When use a gas law, “the gas you put in is the gas you get out”
