46. Solving a chemistry problem

3. 3 g of polystyrene sulfonic cation exchanger in the H-form, the total exchange capacity of which is 5.12 equiv/kg, was introduced into 0.2 l of an aqueous solution of CsCl with an initial concentration of 810-2 mol/l. Determine the equilibrium concentrations of H and Cs ions in the solution and in the ion exchanger if the ion exchange equilibrium constant is 2.7.
