Derive an expression for (as / av), for n moles of a gas obeying the truncated virial equation of
state
PV = 1+
BB

V V
RT
where S is entropy, V is volume, p is pressure, T is temperature, R is the ideal gas constant, Vm is
molar volume, B2 and B3 are virial coefficients that depend on temperature T. Suppose B30, B2 =
-15.8x10-6 mmol'' and dB2/dt = 0.25x10 mmol'' K-, evaluate this expression for 1 mole of
argon in 25 cm at 303.15 K.​
