Amount of electricity that can deposit $108 \ g$ of silver from $AgNO_3$ solution is

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]

In the electrolysis of a fused salt,the weight of the deposit on an electrode will not depend on:

$A$ solution of $CuSO_4$ is electrolysed for $10 \,min$ with a current of $1.5 \,A$. What is the mass of copper deposited at the cathode (in $,g$)?

Two electrolytic cells containing molten solutions of nickel chloride and aluminium chloride are connected in series. If the same amount of electric current is passed through them,what will be the weight of nickel obtained when $18 \ g$ of aluminium is obtained (in $g$)? $[Al = 27 \ g/mol, Ni = 58.5 \ g/mol]$

How many seconds of current at $9.65 \ A$ must be passed through a solution of $Al^{3+}$ to obtain $1 \ \text{millimole}$ of $Al$ metal?
