The amount of silver deposited on passing $2 \ F$ of electricity through an aqueous solution of $AgNO_3$ is: (in $g$)

$A$ constant current $(0.5 \, A)$ is passed for $1 \, hour$ through $(i)$ aqueous $AgNO_3$,$(ii)$ aqueous $CuSO_4$ and $(iii)$ molten $AlF_3$,separately. The ratio of the mass of the metals deposited on the cathode is $[M_{Ag}, M_{Cu}, M_{Al}$ are molar masses of the respective metals.]

When the same quantity of electricity is passed through solutions of different electrolytes connected in series,the amounts of substances deposited at the electrodes are in the ratio of their ...?

In the electrolysis of water,one Faraday of electrical energy would evolve

If solutions of silver nitrate and cupric salt are connected in series and the same current is passed,what will be the weight of copper deposited in $gm$ when $1.08 \ g$ of silver is deposited?

The unit of Faraday is
