Description

At constant pressure and constant temperature, any gas occupies the same volume regardless of the type of atom or the composition. So if we know the volume, pressure and temperature, we can then determine the molar mass of gases. The measurement is conducted in experiment C1.1.1.2 with a glass sphere for weighing gases.
