Type: MCQ-numerical-Medium-Class 12

Mass in grams of copper deposited by passing 9.6487 Å current through a voltmeter containing copper sulphate solution for 100 seconds is: (Given : Molar mass of Cu : 63 g mol⁻¹, 1F = 96487 C)

A

31.5 g

B

0.0315 g

C

3.15 g

D

0.315 g

Correct Answer

Option D

Detailed Explanation

Using the formula m = (ItM)/(nF), where I = 9.6487 Å, t = 100 s, M = 63 g/mol, n = 2, and F = 96487 C/mol, the mass m = 0.0315 g.
