question

Two electrochemical cells were fitted with inert platinum electrodes and connected in series. The first cell contained a solution of a metal nitrate; the second cell, metal sulfate. After operation of the cell for a prescribed period of time, it was observed that 675 mg of the metal had been deposited in the first cell and 76.3 ml of hydrogen gas (25° and 1 atm) evolved in the second. Determine the equivalent weight of the metal.
