Question

1. Consider a glass of water in a room at 27°C and 97 kPa. If the relative humidity in the room is 100 percent and the water and the air are in thermal and phase equilibrium, determine

(a) the mole fraction of the water vapor in the air and

(b) the mole fraction of air in the water.

2. Consider a carbonated drink in a bottle at 27°C and 115 kPa. Assuming the gas space above the liquid consists of a saturated mixture of CO₂ and water vapor and treating the drink as water, determine

(a) the mole fraction of the water vapor in the CO₂ gas and

(b) the mass of dissolved CO₂ in a 300-ml drink.
