The solubility of oxygen in lakes high in the Rocky Mountains is affected by the altitude. If the aqueous solubility of atmospheric O₂ is 2.67 times 10⁻4 M at sea level and 25 degree C. what is the solubility of O₂ at an elevation of 12,000 ft where the total pressure is 0.657 atm? Assume the temperature is 26 degree C. and that the mole fraction of O₂ in air is 0.209 at both 12,000 ft and at sea level.
a)3.66 ×10⁻5 M
b)1.75 ×10⁻4 M
c)2.67 ×10⁻4M
d)4.06 × 10⁻4 M
e)none of the above
