4. The maximum value of n in [Cu(EN),,J for a Cu2+-EN solution is the key to a gravimetric method for determining the amount of Cu in an unknown aqueous solution. In this method, we add excess EN and potassium tetraiodomercurate(II) (K2H8I4) to the solution, and the Cu precipitates as [Cu(EN),] [Hgl4]. Assuming that the Cu is the limiting reagent, what mass of [Cu(EN),] [Hgl4] should be isolated for each milligram of Cu2 in solution? + 2+ 2+
