Exercise $17.$ The solubility of $N_2$ in blood at $37C$ and a partial pressure of $0\mathrm{.}80$atm is $5\mathrm{.}6*{10}^{-4}mo\frac{l}{l}.$ A deep$-$sea diver inhales compressed air at a particle pressure of $N_{2}4\mathrm{.}0$atm. Suppose the volume of blood in a body is $5\mathrm{.}0$ liters. Calculate the amount of $N_2($in litres at $37C$ and $1$atm $)$ emitted when the diver returns to the water surface. The partial pressure of $N_2$ is $0\mathrm{.}80$atm at the water surface.
