The time required (in hours) to reduce $3 \ mol$ of $Fe^{3+}$ ions to $Fe^{2+}$ ions with $2.0 \ A$ of current is $\left(1 \ F = 96500 \ C \ mol^{-1}\right)$ (in $.2$)

Aqueous $CuSO_4$ solution was electrolysed by passing $2 \ A$ of current for $10 \ min$. What is the weight (in $g$) of copper deposited at the cathode? (Given: $Cu = 63 \ u$; $F = 96500 \ C \ mol^{-1}$)

Mass in grams of copper deposited by passing $9.6487 \ A$ current through a voltmeter containing copper sulphate solution for $100 \ s$ is (Given : Molar mass of $Cu: 63 \ g \ mol^{-1}, 1 \ F=96487 \ C$ ) (in $g$)

The number of Faraday required to generate $1$ $g$ $atom$ of $Mg$ from $MgCl_2$ is :-

What is the number of faraday required to form $1 \ mol \ H_2$ by reduction of $H^{+}$ ions?

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 ............ $g$.
