The amount of charge required for obtaining one mole of $Al$ from $Al^{3+}$ is:

The atomic weight of $Al$ is $27$. When a current of $5$ Faradays is passed through a solution of $Al^{3+}$ ions,the weight of $Al$ deposited is ............ $g$.

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

When a current of $10800 \ C$ is passed through an electrolyte,$2.977 \ g$ of a metal is deposited. If the molar mass of the metal is $106.4 \ g \ mol^{-1}$,what is the charge on the metal cation?

To deposit one $gm$ equivalent of an element at an electrode,the quantity of electricity needed is

When $9.65 \ A$ current was passed for $1.0 \ h$ into nitrobenzene in an acidic medium,the amount of $p$-aminophenol produced is .............. $g$.
