in which the temperature-dependent constants for each gas are known as the virial coefficients. The second virial coefficient, B , has units of molar volume (L/mole). This is sometimes replaced with a modified version with different coefficients, PV = nRT[1 + B'P + C'P2 + ...] . Since, the repulsion among gaseous molecules strongly predominates. the van der waals coefficient ′a′ can be neglected.The third viral coefficient C=b2 . . . . . . . . . . . . .
