Calculate the pressure of nitrogen gas (in bar) at 273.15 K when it’s molar volume is 1.00 L mol-1 using: (a) The ideal gas Law. (b) The Van der Waals equation with a = 1.3661 dm6 bar mol-2 and b = 0.038577 dm3 mol-1. (c) The virial equation, assuming B2V(273.15 K) = –0.010 L mol-1. Assume the higher order virial coefficients can be neglected.
