Silver plating is done on a silver cup by passing a current of $965 \ A$ for $1 \ s$. How many grams of $Ag$ are deposited? $(Ag = 107.87 \ g/mol)$

The number of moles of electrons required to deposit $36 \ g$ of $Al$ from an aqueous solution of $Al(NO_3)_3$ is (At. wt. of $Al = 27$)

When a current of $2 \ A$ is passed through a molten salt of a metal for $5 \ hours$,$22.2 \ g$ of the metal (atomic mass $= 177$) is deposited at the cathode. What is the oxidation state of the metal in the molten salt?

Calculate the amount of electricity required in coulombs to convert $0.08 \ mol$ of $MnO_4^{-}$ to $Mn^{2+}$. (in $C$)

If solutions of silver nitrate and cupric salt are connected in series and the same current is passed,what will be the weight of copper deposited in $gm$ when $1.08 \ g$ of silver is deposited?

How many electrons flow when a current of $5 \ A$ is passed through a cell for $200 \ s$?
