A new and relatively unstudied compound is being investigated for its potential use as a refrigerant. The compound has a critical temperature T_c = 500 K and P_c = 30 bar. The vapor pressure at T = 350 K is P^sat = 2.4 bar. Estimate the molar volume of the compound at each of the following conditions.

A. In the liquid phase at T = 350 K and P = 6 bar.

B. In the vapor phase at T = 350 K and P = 2 bar.

C. In the vapor phase at T = 500 K and P = 6 bar.

D. In the liquid phase at T = 300 K and P = 3 bar.
