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 states that the volume of a gas is proportional to the number of moles of the gas when pressure and temperature are kept constant

However, this is a valid statement that under the same conditions of temperature and pressure, equal volumes of different gases contain an equal number of molecules

They are the laws which relates the volume, pressure and temperature of a gas. The gas laws includes:

Therefore, the law which states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant is Avogadro's law
