1. The solubility of a gas is 0.34 g/L at STP. Whatis its solubility at a pressure of 0.80 atm andthe same temperature?2. At 25°C and 1.0 atm, 0.25 g of a gas dissolvesin 1.00 L of water. What mass of the gas dissolvesin 1.00 L of water at 25°C and 3.0 atm?3. 1.56 g of a gas dissolves in 2.00 L of water at apressure of 1.75 atm. At what pressure will2.00 g of the gas dissolve in 2.00 L of water ifthe temperature remains constant?
