Multiple Choice
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.
A) 1.75 * 10-4 M
B) 2.67 * 10-4 M
C) 3.66 * 10-5 M
D) 4.06 * 10-4 M
E) None of the above.
