Why is the identity of a gas not included in the combined and ideal gas law? For example, carbon dioxide has a larger molar mass than hydrogen, yet the molar mass is not included in either the combined gas law or the ideal gas law.
1. Go a step further and discuss what property of a gas IS affected by the identity of a gas.
2. Give some specific laboratory or chemistry problem where the identity of the gas is needed or one where it is not needed.
