You have a container of gas with a molar volume of V¯=0.12 dm3·mol-1 at a temperature of T=280 K. You know that for this gas, 280 K corresponds to a reduced temperature TR=1.5 and that you are applying a reduced pressure of PR=4. Using your knowledge of corresponding states behavior, you look up that the compressibility factor for your gas under these conditions and determine that it should be Z=6/7. What is the second viral coefficient, B2V(T) for this gas?
