Molar volume is the volume occupied by 1...

Molar volume is the volume occupied by 1 mol of any (ideal) gas at standard temperature and pressure (STP : 1 atmospheric pressure, `0^@C`). Show that it is 22.4 litres.

Verified by Experts

For one mole of an ideal gas
`PV=RT`
`V=(RT)/P`
But `R=8.31J//mol e //K, T=273K`
and P =1 atmosphere =`1.013 times 10^5 N//m^2`
So `V=(8.31 times 273)/(1.013 times 10^5)=0.0224 m^3`
`=0.0224 times 10^6 cm^3=22400 ml=22.4l`
