# Velocity of real gas molecules?

It is known that the velocity of ideal gas molecules can be computed using Maxwell-Boltzmann law of distribution of molecular velocities, with average velocity given as:

$\overline{v}=\sqrt{\frac{8RT}{\pi M}}$

What would be the corresponding velocity for a real gas (which are not at STP)? Thanks!

 At STP everyday gasses are pretty close to ideal. – dmckee♦ Nov 26 '12 at 2:58
