The solubility (i.e. the maximum molarity at equilibrium) of N2 gas in blood at 37oC under a nitrogen partial pressure of 0.80 atm is 5.6 x 10-4 mol.L-1. When swimming at large depth in the ocean, a diver breathes compressed air with a partial pressure of N2 equal to 4.0 atm. Henry’s law indicates that the solubility of N2 gas increases with pressure. Assume that the total volume of blood in the body is 5.0 L. Calculate the amount of N2 gas in the diver’s blood before diving. Calculate the amount of N2 gas in the diver’s blood as he is breathing compressed air with a partial pressure of N2 equal to 4.0 atm. Calculate the amount of nitrogen gas (in liters) that must be released when the diver returns to the surface of water, where the partial pressure of N2 is 0.80 atm.

At ordinary body temperature (37 °C), the solubility of N2 in water at ordinary atmospheric pressure (1.0 atm) is 0.015 g/L. Air is approximately 78 mol % N2. (a) Calculate the number of moles of N2 dissolved per liter of blood, assuming blood is a simple aqueous solution. (b) At a depth of 100 ft in water, the external pressure is 4.0 atm. What is the solubility of N2 from air in blood at this pressure? (c) If a scuba diver suddenly surfaces from this depth, how many milliliters of N2 gas, in the form of tiny bubbles, are released into the bloodstream from each liter of blood?

The solubility (i.e. the maximum molarity at equilibrium) of N2 gas in blood at 327.193K under a nitrogen partial pressure of 0.897 atm is 5.69x10-4 mol.L-1 . When swimming at large depth in the ocean, a diver breathes compressed air with a partial pressure of N2 equal to 4.07 atm. Henry’s law indicates that the solubility of N2 gas increases with pressure. Assume that the total volume of blood in the body is 5.0 L. Calculate the amount of nitrogen gas (in liters to the third decimal place) that must be released when the diver returns to the surface of water, where the partial pressure of N2 is 0.897 atm.
