How much metal will be deposited when a current of 12 ampere with 75% efficiency is passed through the cell for 3 h? (Given: Z = 4 × 1 0 - 4 )

Options

  1. A32.4 g
  2. B38.8 g
  3. C36.0 g
  4. D22.4 g

Correct answer

B. 38.8 g

Step-by-step solution

W = Z × I × t = 4 × 1 0 - 4 × 12 × 75 100 × 3 × 3600 = 38.8 g
