# Problem: The solubility of oxygen in lakes in the Rocky Mountains is affected by the altitude. If the solubility of O2 from the air is 2.67 x 10-4 M at sea level and 25°C, what is the solubility of O 2 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.A) 1.75 x 10-4 MB) 2.67 x 10-4 MC) 3.66 x 10-4 MD)4.06 x 10-4 ME) none of the above
