Avogadro's law states that the volume occupied by an ideal gas is directly proportional to the number of molecules of the gas present in the container. This gives rise to the molar volume of a gas, which at STP (273.15 K, 1 atm) is about 22.4 L. The relation is given by:
V1
n1
=
V2
n2
Where V1 and V2 are volume And n1 and n2 are no. of mole
