one coulomb of electrical charge is passed through solutions of AgNo3 & CuSo4 connected in series using platinum electrode . what is the mass ratio of Ag/Cu?

According to Faraday's II law,When same amount of current is passed through different electrolyte, the substancedeposited in each electrode is proportional to their equivalent masses.Mass of Ag depositedMass of Copper deposited = Equivalent mass of AgEquivalent mass of Copper                         = 108 /163.5/2 = 10831.75Thus the ratio of mass of Ag/Cu = 108 / 31.75.                               so ans is (3) approapprox..
