By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.039% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere.
Best Answer: The partial pressure of oxygen in the atmosphere is 1 atm * 21% O2 = 0.21 atm 1 atm, the O2 in the water is 0.00130 M/atm * 0.21 * 1 atm = 0.000273 mole / L 0.894 atm, the O2 in the water is 0.00130 M/atm * 0.21 * 0.894 atm = 0.000244 mole / L If you drop the pressure, the change in solubility is 0.000273 M - 0.000244 M = 0.000029 M Concentration = ...
