Chapter 7, Problem 7.46E

At ${\text{25}}^{\text{ο}}\text{C}$, the mole fraction of nitrogen, ${\text{N}}_{\text{2}}\left(\text{g}\right)$, in water is $1.274\times {10}^{-5}$. (a) Compare this with the number in the previous problem and comment? (b) Calculate the solubility of oxygen, ${\text{O}}_{\text{2}}\left(\text{g}\right)$, in water given the fact that air is approximately $\text{80\%}$ nitrogen and $\text{20\%}$ oxygen. (c) Calculate the Henry’s law constant for oxygen? Compare your answer to the number in Table 7.2.
