The solubility of O2 in water is approximately0.00380 grams per liter of water when the partial pressure of gaseous oxygen is 760 torr and the temperature is 25.0°C. The oxygen gas above the water is replaced by air at the same pressure and temperature, in which the mole fraction of oxygen is 0.210. Explain what should the solubility of oxygen in the water be under these new conditions?
