How to derive that one mole of gas occcupies 22.4 l?

Answer 1

sorry I don't know...

Answer 2

The law is named after Amedeo Avogadro who, in 1811,[2][3] hypothesized that two given samples of an ideal gas, of the same volume and at the same temperature and pressure, contain the same number of molecules. As an example, equal volumes of molecular hydrogen and nitrogencontain the same number of molecules when they are at the same temperature and pressure, and observe ideal gas behavior. In practice, real gases show small deviations from the ideal behavior and the law holds only approximately, but is still a useful approximation for scientists.
