$A$ solution of $CuSO_4$ is electrolysed using a current of $1.5 \ A$ for $10 \ minutes$. What mass of $Cu$ is deposited at the cathode (in $g$)? (Atomic mass of $Cu = 63.7$)

One ampere of current is passed for $9650 \ s$ through molten $AlCl_3$. What is the weight in grams of $Al$ deposited at the cathode? (Atomic weight of $Al = 27$)

When a current of $0.1 \, A$ is passed through $200 \, mL$ of a $0.1 \, N$ $AgNO_3$ solution,silver is deposited. How much time in $sec$ is required to remove half of the silver from the solution?

When an electric current is passed through a silver nitrate solution using silver electrodes,$10.79 \ g$ of silver is deposited. If the same amount of electric current is passed through a copper sulfate solution using copper electrodes,how many grams of copper will be deposited at the cathode (in $g$)?

When $0.04$ faraday of electricity is passed through a solution of $CaSO_4$,then the weight of $Ca^{2+}$ metal deposited at the cathode is $.............$ $g$.

The quantity of charge required to obtain $1 \, mole$ of aluminium from $Al_2O_3$ is ............ $F$.
