Henry's law: saturation of water with oxygen a solution with oxygen dissolved in water containing 0.5 mg 0,/100 g of h. o is brought in contact with a large volume of atmospheric air at 283 k and a total pressure of 1 atm. the henry's law constant for the oxygen-water system at 283 k equals 32,700 atm/mol fraction. (a) will the solution gain or lose oxygen? (b) what will be the concentration of oxygen in the equilibrium solution?
