i have attached an image of the question as it keeps changing my characters in the text box.

Extracted text: For methyl chloride at 120°C the second and third virial coefficients are: B = -242.5 cm 3.mol -1 C = 25,200 cm 6.mol -2Calculate the work of mechanically reversible, isothermal compression of 1 mol ofmethyl chloride from 1 bar to 60bar at 120°C. Base calculations on the following forms of the virial equation: (a)Z=1+BV+CV2 (b)Z=1+B'P+C'P2 where B' = B/RTand C'=(C-B2)/(RT)2 (c) Why don't both equations give the same result?
