The molar mass of an ideal gas is directly proportional to its density. This property has long been used in laboratory experiments in which a flask is filled with the vapor of a volatile liquid, and the mass, volume, temperature, and pressure of the vapor are used to find the molar mass of that vapor. In a related approach, the difference in the mass between a sample of carbon dioxide and a sample ...
