If the electrochemical equivalent of a substance is $0.0006735 \ g/C$,what is its equivalent weight?

How many coulombs are required for the oxidation of $2 \, mol$ of $H_2O_2$ to $O_2$?

$Al_2O_3$ is reduced by electrolysis at low potentials and high currents. If $4.0 \times 10^4$ amperes of current is passed through molten $Al_2O_3$ for $6$ hours,what mass of aluminium is produced? (Assume $100\%$ current efficiency,at. mass of $Al = 27 \ g \ mol^{-1}$).

To complete the precipitation of $Ag$ from $400 \ mL$ of $0.04 \ M$ $AgNO_3$ solution,how long should a $4.8 \ A$ current be passed?

Clarify the stoichiometry of the reactions occurring on the electrodes of an electrolytic cell and its relationship with the quantity of electricity.

The electrochemical equivalent of magnesium is $0.126 \ mg/C$. $A$ current of $5 \ A$ is passed in a suitable solution for $1 \ hour$. The mass of magnesium deposited will be ........... $gm$.
