At 25°C, the mole fraction of nitrogen, N₂ (g), in water is 1.274 x 10^-5. (a) Compare this with the number in the previous problem and comment. (b) Calculate the solubility of oxygen, O2 (g), in water given the fact that air is approximately 80% nitrogen and 20% oxygen. (c) Calculate the Henry’s law constant for oxygen. Compare your answer to the number in Table 7.2.
