All air is removed (vacuumed) from a 2 liter closed container that contains 200 ml of Liquid A and 600 ml of Liquid B at a temperature of 20C. At this temperature Liquid A has a density of 0.825 g/ml and vapor pressure of 25 kPa. Liquid B has a density of 0.750 g/ml and vapor pressure of 15 kPa. What is the mol fraction of vapor from Liquid A in the head space above the liquid surface? A) .25 B) .38 C) .63 D) .75
