We have two cells with inert electrodes. Cell 1 contains a solution of cuprum (II) sulfate with an amount of substance of 2 mol. The cell 2 contains a solution of cuprum (II) sulfate with a substance amount of 3 mol. Through the cells connected in series, they passed a current of 6F (Faraday). Calculate the mass of substance that will be released on the cathodes of each cell
