A copper cell containing `5%` solution of `CuSO_(4).5H_(2)O` and a silver cell contaning a `2%` solution of `AgNO_(3)` by weight are connectged in series. A current of `0.01` ampere was passed through the cells for `30` minute. What was the ratio of mass of `Cu` and `Ag` deposited at the cathode of cell? `At. wt.` of `Cu` and `Ag` arte `63.6` and `108` respectively.
