E10. THE IDEAL GAS EQUATION: pV = n R T - PRACTICE PROBLEMS
One of the most important applications of the ideal gas equation is in the determination of molar masses of gases and volatile liquids. Two useful relationships are derived below from three equations that the reader will be familiar with already.
Instead of providing values of pressure and volume, questions involving the ideal gas equation might give the pressure and density and demand calculation of molar mass. In this case we have to make use of the relation m = r V.
