As a scuba diver descends under water, the pressure increases. At a total air pressure of 2.89 atm and a temperature of 25.0 celcius, what is the solubility of N_2 in a diver's blood? [Use the value of the Henry's law constant k calculated in Part A, 6.26* 10^{-4}\; mol/(L\ atm).]
Assume that the composition of the air in the tank is the same as on land and that all of the dissolved nitrogen remains in the blood.
