Definition of Avogadro’s law:

Avogadro’s law (sometimes referred to as Avogadro’s hypothesis or Avogadro’s principle) is an experimental gas law relating volume of a gas to the amount of substance of gas present.[1] A modern statement of Avogadro’s law is:

Avogadro’s law states that, “equal volumes of all gases, at the same temperature and pressure, have the same number of molecules”.

For a given mass of an ideal gas, the volume and amount (moles) of the gas are directly proportional if the temperature and pressure are constant.
