At 273K measurements on Argon gave B = -21.7cm3/mol and C = 1200cm6/mol2, where B and C are the 2nd and 3rd viral coefficients in the expansions of Z in powers of 1/Vm. Pretentious that the perfect gas law holds sufficiently well for the estimation of the 2nd as well as 3rd terms of the expansion, compute the compression factor of Argon at 100atm and 273K. Approximate the molar volume of Argon under these conditions.
