8. What is the difference in blood oxygen concentration between a person at sea level where the air pressure is 1.0 atm and the top of K2, where the total air pressure is 34.7 kPa? (You can assume the mole fraction of oxygen in air remains constant at 0.2
1. What is the difference in blood oxygen concentration between a person at sea level where the air pressure is 1.0 atm and the top of K2, where the total air pressure is 34.7 kPa? (You can assume the mole fraction of oxygen in air remains constant at 0.21 (or 21% of the total air pressure is oxygen), the temperature is 37 C, and that the solubility of oxygen in blood at 37 C is approximately 1.0 x 10-3 mol/L-atm.)
