At an altitude of 10,000 ft the partial pressure of oxygen in the lungs is about 68 mm Hg. What is the concentration (in mg/L) of dissolved O2 in blood (or water) at this partial pressure and a normal body temp of 37 C? The solubility of O2 in water at 37 C and 1 atm partial pressure is 1.93 x 10^-3 mol/L.
