According to Faraday's laws of electrolysis,the amount of decomposition is proportional to

$A$ solution of $Ni(NO_{3})_{2}$ is electrolysed between platinum electrodes using a current of $5 \, A$ for $20 \, minutes$. What mass of $Ni$ is deposited at the cathode (in $, g$)?

When the same quantity of electricity is passed through aqueous $AgNO_3$ and $H_2SO_4$ solutions connected in series,$5.04 \times 10^{-2} \ g$ of $H_2$ is liberated. What is the mass of silver (in grams) deposited? (Eq. wts. of hydrogen $= 1.008$,silver $= 108$)

When a certain amount of electricity is passed through a solution of $Al^{3+}$,$4.5 \ g$ of aluminum (atomic mass $27 \ amu$) is deposited at the cathode. If the same amount of electricity is passed through $H^{+}$ ions,what volume of hydrogen (in $L$) is produced at $STP$?

The relation between Faraday constant $(F)$,chemical equivalent $(E)$,and electrochemical equivalent $(Z)$ is

The value of one Faraday is .............. $C \ mol^{-1}$.
