Question

The mass density of water vapor at 327.6 atm and 776.4K is 1.332X10^2 g/L. Given that for water Tc= 674.4K, Pc= 218.3 atm, a= 5.464 L^2 atm/ mol^-2, b= 0.0305 L/mol, and M= 18.02 g/mol; calculate the molar volume. Next, caculate the compression factor from this data and also calculate the compression factor from the virial expansion of the van der waals equation.
