This is the molar volume at

  • standard pressure po= 1 ATM (= 101.325 kPa)

and at

  • standard temperature (melting ice) T= 273.15 K

(At room temperature T= 298 K and p= po the molar volume is 24.5 L/mole)

At standard temperature (melting ice) T = 273.15 K

and standard pressure po= 1 ATM (= 1.01325*105 Pa)

Molar volume = 22.4141 L/mole(At room temperature T=298 K and p=po the molar volume is 24.5 L/mole)

This is exactly true only for hypothetical ideal gases, but is very close for several actual gases, particular the noble gases.

1 mole of any gas at STP is 22.4L, so 22.4L of nitrogen gas is 1 mole of nitrogen gas.
