c = p*K
For O2, c = 1.3E-3 mol/L*atm x (0.2) and
for N2, c = 6.8E-4 mol/L*atm x (0.8).
Add to find total mols, then
XO2 = nO2/total mols
XN2 = nN2/total mols.
Fish breathe the dissolved air in water through their gills. Assuming the partial pressures of oxygen and nitrogen in the air are to be .20 atm and .80 atm respectively, calculate the mole fractions of oxygen and nitrogen in the air dissolved in water at 298 k. The solubilities of oxygen and nitrogen in water at 298 k are 1.3 x 10^-3 mol/lxatm and 6.8 x 10^-4 mol/lxatm respectively.
