###### Problem Details

Fish breathe the dissolved air in water through their gills. Assuming the partial pressures of Nand O2 in air to be 0.80 atm and 0.20 atm, respectively, calculate the concentrations of oxygen and nitrogen in water at 298 K. Henry’s law constant for N2 (g) and O2 (g) in water at 298 K are 6.8 x 10-4 and 1.3 x 10-3 mol L-1 atm-1, respectively.

Select the concentration of Nitrogen in water.
