When $0.04$ faraday of electricity is passed through a solution of $CaSO_4$,then the weight of $Ca^{2+}$ metal deposited at the cathode is $.............$ $g$.

In an electroplating experiment,$m \ g$ of silver is deposited when $4 \ A$ of current flows for $2 \ min$. The amount (in $g$) of silver deposited by $6 \ A$ of current flowing for $40 \ s$ will be:

On passing $0.5 \ F$ of electricity through $NaCl$,the amount of $Cl_2$ gas deposited at the anode is .............. $g$.

How much charge is required for the deposition of $1$ equivalent of a substance?

Salts of $A, B$ and $C$ were electrolysed under identical conditions using the same quantity of electricity. It was found that when $2.1 \ g$ of $A$ was deposited,the weights of $B$ and $C$ deposited were $2.7 \ g$ and $9.6 \ g$. If the atomic mass of $A, B$ and $C$ are $7, 27$ and $64$ respectively,then the valencies of $A, B$ and $C$ respectively are:

How many atoms of calcium will be deposited from molten $CaCl_2$ by a current of $25 \, mA$ flowing for $60 \, s$?
