$96500 \ C$ of electric charge liberates how many grams of $Cu$ from $CuSO_4$ solution?

The mass of silver (Molar mass of $Ag: 108 \ g \ mol^{-1}$) displaced by a quantity of electricity which displaces $5600 \ mL$ of $O_2$ at $S.T.P.$ will be . . . . . . $g$.

When a current of $0.1 \, A$ is passed through $200 \, mL$ of a $0.1 \, N$ $AgNO_3$ solution,silver is deposited. How much time in $sec$ is required to remove half of the silver from the solution?

How many faraday are needed to reduce a mole of $MnO_4^-$ to $Mn^{2+}$?

From which solution $2 \ F$ electrical charge will deposit $1 \ g$ atomic weight at cathode?

In the electrolysis of acidulated water,it is desired to obtain $1.12 \ cc$ of hydrogen gas per second at $STP$ conditions. The current to be passed is: (in $A$)
