Problem
A solution containing trivalent cations of an unknown metal is electrolyzed with a steady current of 3.00 A for 20.0 min. Only 85 % of the charge contributes to metal deposition; the remainder drives oxygen evolution at the anode. If 2.50 g of metal is obtained, calculate the molar mass of the metal. (Assume F=9.65×104C mol−1.)
