The law that 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. That is option D.
Avogadro’s law states that the volume of a gas is proportional to the moles of the gas when pressure and temperature are kept constant.
Mathematically the Avogadro’s law can be represented by the following:
V1/n1= V2/n1
Where,
V1 = first volume
n1 = first amount of gas
V2 = second volume
n2 = second amount of gas
