Express the van der Waals equation of state as a virial expansion in powers of 1/Vm and obtain expressions for B and C in terms of the parameters a and b. The expansion you will need is
(1-x)-1 = 1 + x + x2 + ...
Measurements on argon gave B = -2.17 cm3 mol-1 and C = 1200 cm6 mol-2 for the virial coefficients at 273 K. What are the values of a and b in the corresponding van der Waals equation of state?
van der Waals equation: p = nRT/(V-nb) - a(n/V)2

Not sure how to approach this...
Thanks! This pset is due tomorrow morning so please help! :(
