The number of electrons delivered at the cathode, during electrolysis by a current of 1   ampere   in   60   seconds is (charge on electron = 1.60 × 10 - 19   C )

Options

  1. A6 × 10 23
  2. B6 × 10 20
  3. C3.75 × 10 20
  4. D7.48 × 10 23

Correct answer

C. 3.75 × 10 20

Step-by-step solution

Q = I × t = 1 A × 60 s = 60   C ∴ Number of electrons = 60 1.602 × 10 - 19 = 3.75 × 10 20
