For the system of acetone(l) and nhexane(2) at 20C, the following data are available: E % : x1x2(1.7448x1+1.8012x2) Pf\" : 24.20 kPa 132sat :1595 kPa At 20C calculate the total pressure and vapor composition which would be in equilibrium with liquid mixtures at each of the following compositions: x1 = 0.10, x1 = 0.63, & x1 = 0.90. Assume that the vapor phase behaves ideally. Based on these calculations, how would you characterize this binary system
