When the same quantity of electricity is passed through solutions of different electrolytes connected in series,the amounts of substances deposited at the electrodes are in the ratio of their ...?

Faraday's laws of electrolysis state that the mass deposited on an electrode is proportional to:

When an electric current is passed through a silver nitrate solution using silver electrodes,$10.79 \ g$ of silver is deposited. If the same amount of electric current is passed through a copper sulfate solution using copper electrodes,how many grams of copper will be deposited at the cathode (in $g$)?

To complete the precipitation of $Ag$ from $400 \ mL$ of $0.04 \ M$ $AgNO_3$ solution,how long should a $4.8 \ A$ current be passed?

When $X$ amperes of current is passed through molten $AlCl_3$ for $96.5$ $s$,$0.09$ $g$ of aluminium is deposited. What is the value of $X$?
