$1 \ F$ current means $...$ Coulomb electricity. (in $C$)

How many electrons would be required to deposit $6.35 \ g$ of copper at the cathode during the electrolysis of an aqueous solution of copper sulphate? (Atomic mass of copper $= 63.5 \ u$,$N_A =$ Avogadro's constant)

Passage of a current for $548 \, s$ through a silver coulometer results in the deposition of $0.746 \, g$ of silver. What is the current (in $A$)?

When the same quantity of electricity is passed through aqueous $H_2SO_4$ and molten $MgSO_4$,what is the ratio of the weights of hydrogen and magnesium deposited?

Three faradays of electricity are passed through molten $Al_2O_3$,aqueous solution of $CuSO_4$ and molten $NaCl$ taken in different electrolytic cells. The amount of $Al$,$Cu$ and $Na$ deposited at the cathodes will be in the ratio of

Alkanes can be prepared by the electrolysis of an aqueous solution of the potassium salt of a carboxylic acid (Kolbe's electrolysis). Find the total weight of all gases evolved at $STP$ by passing a $20 \ A$ current for $9650 \ s$ during the electrolysis of $CH_3COOK_{(aq)}$. [Ignore parallel or side reactions]
