The mass density of water vapour at 327.6 atm and 776.4 K is 133.2 kg m−3. Given that for water a = 5.464 dm6 atm mol−2, b = 0.03049 dm3 mol−1, and M = 18.02 g mol−1, calculate (a) the molar volume. Then calculate the compression factor (b) from the data, and (c) from the virial expansion of the van der Waals equation.
