If you place 1.66g of CuS(s) into a beaker of distilled water, what will be the cation(aq) concentration (in molarity) at equilibrium? if you place the same amount (1.66g) of CuS(s) in a beaker now containing a solution of .088M CuSO4, what will the equilibrium concentration of the cation (aq) in Molarity?
