Henry’s Law 1. A gas has a solubility of 0.086 g/L at a pressure of 3.5 atm. At what pressure would its solubility be 2.3 g/L? 2. T he solubility of a gas changes from 0.95 g/L to 0.72 g/L. If the initial pressure was 2.8 atm, what is the final pressure? 3. T he solubility of a gas in water is 0.220 g/L at 20.0 kPa of pressure. What is the solubility when the pressure is increased to 115 kPa? 4. T he solubility of a gas in water is 0.66 g/L at 15 kPa of pressure. What is the solubility when the pressure is increased to 40.0 kPa? 5. T he solubility of a gas is 2.0 g/L at 50.0 kPa of pressure. How much gas will dissolve in 1.0 L at a pressure of 10.0 kPa? 6. T he solubility of a gas is 4.50 g/L at a pressure of 1.00 atm. At what pressure will there be 45.0 g of a gas in 1.00 L of a solution? 7. T he partial pressure of CO2 inside a bottle of soft drink is 4.0 atm at 25oC. The solubility of CO2 is 0.12 mol/L. When the bottle is opened, the partial pressure drops to 3.0 x 10-4 atm. What is the solubility of CO2 in the open drink? Express your answer in grams per liter. 8. If 0.24 g of a gas dissolves in 1.0 L of water at 1.5 atm of pressure, how much of the gas will dissolve if the pressure is raised to 6.0 atm? Assume the temperature is held constant. 9. If 0.55g of a gas dissolves in 1L of water at 20 kpa of pressure, how much will dissolve at 110 kpa of pressure? 10.A gas has a solubility of 0.660 g/L at 10.0 atm pressure. What is the pressure on a 1.00 L sample that contains 1.50 g of gas? 11.The solubility of a gas is 2.0 g/L at 50. kpa of pressure. How much gas will dissolve in 1.0 L at a pressure of 10. kpa? nswers: 1) 94 atm 2) 2.1 atm 3) 1.27 g/L 4) 1.8 g/L 5) 0.40 g 6) 10.0 atm 7) 4.0 x 10-4 g/L A 8) 0.96 g/L 9) 3 g/L 10) 22.7 atm 11) 0.40 g/L
