    I got [tex]\dfrac{RT}{1-\frac{2a}{V^3}\frac{(V-b)^2}{RT}}[/tex]. But I'm happy enough that I know how to solve the problem should it come up. Thanks guys.

    There should not be a T in the numerator.

    I got it from [tex]T \Bigg{(}\dfrac{\partial p}{\partial T}\Bigg{)}_V[/tex]

    I couldn't get an [itex]R[/itex] on its own

    Too bad. Check the units on your expression for the difference between the heat capacities. It doesn't have the correct units.
