chpt.9 pg 11: Pressure and temperature affect the amount of space between gas molecules, which affects the volume and, therefore, the density of the gas since density=massvolume The molar mass of a substance, however, is a constant and can be used to identify an unknown gas sample. Molar mass is found by dividing the mass of a sample (in grams) by the number of moles in that sample. The number of moles of gas can be calculated using the ideal...
