Correct Answer: Option D

Explanation

M = \(\frac{\text{Molar mass × Quantity of Electricity}}{\text{96500 × no of charge}}\)

= \(\frac{MmIT}{96500n}\)

Copper II Chloride = CuCl₂

CuCl₂ → Cu²⁺ + 2Cl²

Mass of compound deposited = \(\frac{\text{Molar mass × Quantity of Electricity}}{\text{96500 × no of charge}}\)

Q = IT

I = 0.5A

T = 45 × 60

T = 2700s

Q = 0.5 × 2700

= 1350c

Molarmass = 64gmol^-1

no of charge = + 2

Mass = \(\frac{64 \times 1350}{96500 \times 2}\)

Mass = 0.448g
