Leybold Determination of the Molar Mass of Gases

Leybold Chemistry Experiments.

• Show that gases also have a weight
• Determine the molecular mass of gases
• Learn about the molar volume

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.
