Consider a glass of water in a room at 20°C and 100 kPa. If the relative humidity in the room is 70 percent and the water and the air are at the same temperature, determine (a) the mole fraction of the water vapor in the room air, (b) the mole fraction of the water vapor in the air adjacent to the water surface, and (c) the mole fraction of air in the water near the surface.

Answers: (a) 1.64 percent, (b) 2.34 percent, (c) 0.0015 percent
