Which law states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant? boyle’s law dalton’s law charles’s law avogadro’s law

Avogadro's law.

Avogaro's law was first stated in 1811. It states that equal volume of gases at the same temperature and pressure have the same number of molecules.

It is very interesting because it implies that, let's say, 1000 molecules of different gases, like CO2, O2, Kr and He, occupy the same volume at the same temperature and pressure.
