In acidic medium,$MnO_4^-$ is converted to $Mn^{2+}$ when it acts as an oxidant. The quantity of electricity required to reduce $0.06 \ mol$ of $MnO_4^-$ would be ........... $F$.

For electroplating,$1.5 \ A$ current is passed for $250 \ s$ through $250 \ mL$ of $0.15 \ M$ solution of $MSO_4$. Only $85 \ \%$ of the current was utilised for electrolysis. The molarity of $MSO_4$ solution after electrolysis is closest to $.......$ [Assume that the volume of the solution remained constant] (in $M$)

The amount of charge required for obtaining one mole of $Al$ from $Al^{3+}$ is:

What is the number of faraday required to produce $0.18 \ g$ aluminium at cathode during electrolysis of molten $AlCl_3$ (in $F$)? (Molar mass of $Al = 27 \ g \ mol^{-1}$)

When a current of $2 \ A$ is passed through a molten tin salt for $5 \ hours$,$22.2 \ g$ of tin is deposited. What is the oxidation state of tin in the salt? (Atomic weight of $Sn = 118.69$)

Copper is a divalent metal. The value of its electrochemical equivalent is $3.29 \times 10^{-4} \ g/C$. Its atomic mass is (in $g/mol$)
