3. Determine the volume occupied by 36.2 grams of carbon dioxide gas at STP. Molar mass of CO2 = 44.0 g/mol. Use above STP conditions.
Formula PV = (m/M)nRT where m = mass of sample and M = molar mass of substance.

Ascientist measures the speed of sound in a monatomic gas to be 449 m/s at 20∘c. what is the molar mass of this gas?
