A simple and efficient analytical formula for the calculation of second virial coefficient over Sutherland

potential is derived. The compute conclusions of the second virial coefficient determined for

Sutherland potential are compared with calculations of second virial coefficient using Lennard-Jones

(12-6) potential and Exp-6 potential. The accuracy of the analytical formula is tested by application to

molecules Kr, Xe,Ne and Ar . The results of the calculations for wide temperature range show

excellent agreement with the data existing in the literature.
