A constant amount of current flows for 1.5 hours through two
electrolytic cells connected in series. The first cell contains a
solution of FeCl3 and the other contains a solution of MgCl2. If
the first cell increased by 2.30-g in the cathode, what would be
the corresponding increase in the cathode for the second cell? (AW
Fe = 55.845, Mg = 24.305, Cl = 35.45).
