Chemistry - Electrochemistry Question with Solution | TestHub

Two different electrolytic cells filled with molten$\mathrm{C}\mathrm{u}({\mathrm{N}\mathrm{O}}_3{)}_2$and molten$\mathrm{A}\mathrm{l}({\mathrm{N}\mathrm{O}}_3{)}_3$respectively are connected in series. When electricity is passed$\text{2}\text{.7}\text{g}\text{Al}$is deposited on electrode. Calculate the weight of$\text{Cu}$deposited on cathode.

$[\mathrm{C}\mathrm{u}=63.5;\mathrm{A}\mathrm{l}=27.0\mathrm{ }\mathrm{g}\mathrm{ }{\mathrm{m}\mathrm{o}\mathrm{l}}^{-1}]$
