$A$ solution of $CuSO_4$ is electrolysed for $10 \,min$ with a current of $1.5 \,A$. What is the mass of copper deposited at the cathode (in $,g$)?

$A$ metal surface of $100 \, cm^2$ area has to be coated with a nickel layer of thickness $0.001 \, mm$. $A$ current of $2 \, A$ was passed through a solution of $Ni(NO_3)_2$ for '$x$' seconds to coat the desired layer. The value of $x$ is $.........$. (Nearest integer)
($\rho_{Ni}$ (density of Nickel) is $10 \, g \cdot cm^{-3}$,Molar mass of Nickel is $60 \, g \cdot mol^{-1}$,$F = 96500 \, C \cdot mol^{-1}$)

The amount of charge required to liberate $11.5 \ g$ of sodium is .....

Faraday's laws of electrolysis are related to

An electric current is passed through silver nitrate solution using silver electrodes. $10.79 \ g$ of silver was found to be deposited on the cathode. If the same amount of electricity is passed through copper sulphate solution using copper electrodes,the weight of copper deposited on the cathode is ............. $g$

$A$ silver cup is plated with silver by passing $965 \ C$ of electricity. The amount of silver deposited is ............. $g$.
