AP Chemistry - Henry's Law 1. State Henry's Law in your own words. 2. The solubility of methane, the chief component of Bunsen burner gas, in water at 20oC and 1 atmosphere of pressure is 0.025 g/L.  What will be its solubility at 1.4 atm and 20oC? 3. At 98.66 kPa and 20oC nitrogen has a solubility in water of 0.018 g/L. At 82.66 kPa and 20oC, it's solubility is 0.015 g/L.  Does nitrogen obey the gas pressure-solubility law? 4. What makes ammonia so much more soluble in water than nitrogen? 5. What makes carbon dioxide more soluble in water than oxygen? 6. How many grams of nitrogen and oxygen are dissolved in 100 g of water at 20oC when the water is saturated with air?  Above this solution, at a total pressure of 101.325 kPa, the air is saturated with water vapor and the partial pressure of nitrogen is 78.13 kPa and the partial pressure of oxygen is 20.80 kPa.  The solubility of oxygen in water at a total pressure of 101.325 kPa is 0.00430 g O2 / 100 g H2O.  The solubility of nitrogen in water at a total pressure of 101.325 kPa is 0.00190 g N2 / 100 g H2O.
