Three electrolytic cells A, B and C containing electrolytes `ZnSO_4`, `AgNO_3` and `CuSO_4` respectively were connected in series. A steady current of 1.5A was passed through them. 1.45g Ag were deposited at the cathode of cell B.What mass of copper and zinc were deposited? (Atomic mass of Cu = 63.5u, Zn = 65.3u, Ag = 108u.)

Two elements A and B form compounds having formula AB_2 and AB_4 . When dissolved in 20 g of benzene (C_6H_6) , 1 g of AB_2 lowers the freezing point by 2.3 K whereas 1.0 g of AB_4 lowers it by 1.3 K. The molar depression constant for benzene is 5.1 K kg mol^-1 . Calculate atomic masses of A and B.
