What will be the molar volume of nitrogen and argon at 273.15 K and 1 atm?
When temperature and pressure of a gas is 273.15 K (or ) and 1 atm (or 1 bar or pascal), such conditions are called standard temperature and pressure conditions (STP). Under these conditions, the volume occupied by 1 mole of each and every gas is 22.4L. Hence, the molar volume of N2 and Ar at 273.15 K and 1 atm is 22.4L.
