The solubility of oxygen in lakes high in the Rocky Mountains is affected by the altitude. If the solubility of O2 from the air is 2.67 × 10-4 M at sea level and 25°C, what is the solubility of O2 at an elevation of 12,000 ft where the atmospheric pressure is 0.657 atm? Assume the temperature is 25°C, and that the mole fraction of O2 in air is 0.209 at both 12,000 ft and at sea level.

1. 1.75 × 10-4 M 2. 2.67 × 10-4 M 3. 3.66 × 10-5 M 4. 4.06 × 10-4 M 5. none of these
