At an altitude of 10000 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 temperature of 37 degrees C? The solubility of O2 in water at 37 degrees C and 1 atm partial pressure is 1.93 *10^-3 mol/L.
