(Mass transfer). A bowl of water is located in a room. The water is at equilibrium with the air in the room. The room temperature and pressure are 100 kPa and 300 K, respectively. Analysis of water shows that it contains 25 ppm (by weight) of dissolved CO₂. Find the mass fraction and partial pressure of CO₂
in the air.
