What mass of $Mg$ is produced during electrolysis of molten $MgCl_2$ by passing $2 \ A$ current for $482.5 \ s$ (in $g$)? $(Molar \ mass \ Mg = 24 \ g \ mol^{-1})$

Faraday's laws of electrolysis are related to the

The number of Faradays $F$ required to produce $20 \ g$ of calcium from molten $CaCl_2$ (Atomic mass of $Ca = 40 \ g \ mol^{-1}$) is

When the same quantity of electricity is passed through aqueous $H_2SO_4$ and molten $MgSO_4$,what is the ratio of the weights of hydrogen and magnesium deposited?

Faraday's laws of electrolysis are related to

$A$ current of $19296 \ C$ is passed through an aqueous solution of copper sulphate using copper electrodes. What is the mass (in $g$) of copper deposited at the cathode? (Molar mass of $Cu = 63.5 \ g \ mol^{-1}$)
