Well, you'll have to give your equation of state if you want my answer to be more accurate... But since you did not mention ideality, I will have to assume an ideal gas...
We also utilize the latest RTP and STP from IUPAC:
- RTP:
25∘C and1 bar , just like for the thermodynamic standard state - STP:
0∘C and1 bar , after 1982, i.e. today...
And thus, its MOLAR volume is given by
¯¯¯VidRTP=RTRTPP
=(0.083145 L⋅bar/mol⋅K)(298.15 K)1 bar
= 24.790 L/mol
or
¯¯¯VidSTP=RTSTPP
=(0.083145 L⋅bar/mol⋅K)(273.15 K)1 bar
=273.15298.15¯¯¯VidRTP
= 22.711 L/mol
