The law stating that equal volumes of all gases, at the same temperature and pressure, contain the same number of molecules is known as Avogadro’s Law. It was proposed by Italian scientist Amedeo Avogadro in 1811. This law is a key principle in chemistry and relates the volume of a gas to the number of moles (and thus the number of particles) present.

Avogadro’s Law relates the volume of a gas to the number of particles (molecules or atoms) under constant temperature and pressure conditions.

Boyle’s Law relates pressure and volume (at constant temperature and number of particles). Charles’s Law relates volume and temperature (at constant pressure and number of particles). Gay-Lussac’s Law relates pressure and temperature (at constant volume and number of particles). These laws, along with Avogadro’s Law, combine to form the ideal gas law (PV = nRT).
