Henry's Law

Q. Air is a mixture of gases that is about 78.0% N2 by volume. When air is at standard pressure and 25.0 ∘C, the N2 component will dissolve in water with a solubility of 4.88×10−4 M. What is the value of Henry's law constant for N2 under these conditions?

Henry's Law

Q. The solubility of N2 in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 × 10−4 mol/L. A deep-sea diver breathes compressed air with the partial pressure of N2 equal to 5.1 atm. Assume that the total volume of blood in the body is 5.4 L. Calculate the amount of N2 gas released (in liters at 37°C and 1.00 atm) when the diver returns to the surface of the water, where the partial pressure of N2 is 0.80 atm.

Henry's Law

Q. A scientist looking to remove oxygen from above a liquid sample pumps nitrogen into a sealed compartment to displace the oxygen, then places his liquid sample into the compartment. If the nitrogen pressure (partial pressure) was 1.8 atm, what would be the concentration of dissolved nitrogen gas if the Henry’s Law constant for nitrogen gas was 6.8 × 10-4 M atm-1 at this temperature?
