Could someone please provide some assistance as to how to approach this problem. I am doing a thermochemistry lab: The second Virial coefficient of CO2 and I am not sure how to approach this problem. Just a few hints would really be appreciated.

I have tried differentiation, integrals no luck on coming up with the equation they requ

Handwritten-style derivation, typeset in blue: given dH/dP = -Cp muJT = V - T(dV/dT)_P, show that muJT = [T(dB2/dT) - B2] / Cp,m for a gas with PVm = RT + B2 P.
