Two electrolytic cells one containing $Al{Cl}_3$ solution and the other containing $Zn{SO}_4$ connected in series . The same quantity of electricity is passed between in the cells.Calculate the amount of Zn deposited in $Zn{SO}_4$ cell if 1.2 g of Al are deposited in $Al{Cl}_3$ cell. The molar masses of Al and Zn are 27 g ${mol}^{-1}$ and 65.4 g ${mol}^{-1}$ respectively.
