96.5 amperes current is passed through the molten $$\mathrm{AlCl}_3$$ for 100 seconds. The mass of aluminium deposited at the cathode is (atomic weight of $$\mathrm{Al}=27 \mathrm{u}$$)

38.6 amperes of current is passed for 100 seconds through an aqueous $$\mathrm{CuSO}_4$$ solution using platinum electrodes. The mass of copper consumed from the solution and volume of gas liberated at STP are respectively (molar mass of $$\mathrm{Cu}=63.54 \mathrm{~g} \mathrm{~mol}^{-1}$$).

The reduction potential of hydrogen electrode at $$25^{\circ} \mathrm{C}$$ in a neutral solution is ($$p_{\mathrm{H}_2}=1$$ bar)

In the electrolysis of a CuSO$$_4$$ solution, how many grames of Cu are plated out on the cathode, in the time that is required to liberate 5.6 L of O$$_2$$(g), measured at 1 atm and 273 K, at the anode?
