Separation process. Urgent. please help me with full handwritting solution. Please dont take answers from other source. Thank you

A waste acidic stream contains copper in solution which is being removed by a strong acid-cation resin. The cation Cu2+ (A) is displacing the cation H+ (B) in the resin. A polystyrene resin similar to the Table given is being used. The total resin capacity Q is approximately 1.9 equivalents/L of wet bed volume. For a total concentration C of 0.10 N (0.10 equivalents/L) in the solution, calculate at equilibrium the total equivalents of Cu2+ in the resin when the concentration of Cu2+ in solution is 0.02M (0.04 N).
