WebAccording to Henry’s law, for an ideal solution the solubility, Cg, of a gas (1.38 × 10 −3 mol L −1, in this case) is directly proportional to the pressure, Pg, of the undissolved gas above the solution (101.3 kPa in this. case). Because both Cg and Pg are known, this relation can be rearragned and used to solve for k. C g = kP g. cipher\\u0027s wl
