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 4.4 atm. Assume that the total volume of blood in the body is 5.0 L. Calculate the amount of N2 gas released (in liters at 37° C and 1.5 atm) when the diver returns to the surface of the water, where the partial pressure of N2 is 0.80 atm.
