Answer:

Electrolysis is a process of decomposing a compound into its constituent elements using electricity. The amount of element deposited during electrolysis depends on the amount of electricity passed through the solution.

Given, 1 mole of Al is deposited by X coulomb of electricity passing through aluminum nitrate solution.

We know that the charge required to deposit one mole of a substance during electrolysis is given by Faraday's First Law of Electrolysis.

Q = nF

Where Q is the electrical charge passed through the solution, n is the number of moles of the substance deposited, and F is the Faraday constant (96500 C/mol).

For aluminum, n = 1 and Q = XF.

Now, we need to find the number of moles of silver deposited by X coulomb of electricity from silver nitrate solution.

The molar mass of silver is 107.87 g/mol.

Using Faraday's First Law of Electrolysis, we can calculate the number of moles of silver deposited as follows:

Q = nF

X = nF/Ag

nAg = XF/Ag

nAg = X/(F/Ag)

nAg = X/0.001118

nAg = 893.3

Therefore, the number of moles of silver deposited by X coulomb of electricity from silver nitrate solution is 893.3/1000 = 0.8933 ≈ 3 (approx.)

Hence, the correct answer is option 'A' - 3.
