What current strength in $amp$ will be required to liberate $10 \ g$ of chlorine from $NaCl$ solution in one hour?

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 $M$)

How many coulombs are required for the oxidation of $1 \, mol$ of $H_2O_2$ to $O_2$?

The electrochemical equivalent of a metal is $x \ g \ C^{-1}$. The equivalent weight of the metal is:

For how much time,$10 \ A$ electric current should be passed through a dilute aqueous $NiSO_4$ solution during electrolysis using inert electrode,in order to get $5.85 \ g$ Nickel (in $s$)?
[At. mass of $Ni = 58.5 \ g/mol$]

How many $L$ of chlorine gas will be deposited at $NTP$ when a current of $100 \, A$ is passed through molten $NaCl$ for $5 \, hours$?
