How many electrons are delivered at the cathode during electrolysis by a current of 1 ~A in 60 seconds?

Options

  1. A3.74 10²⁰
  2. B6.0 10²³
  3. C7.48 10²¹
  4. D6.0 10²⁰

Correct answer

A. 3.74 10²⁰

Step-by-step solution

Charge = current time Charge, Q=1 ~A 60 sec =60 coulumb Now, 96500 C charge is carried by 6.023 10²³ electron aligned 60 C charge & = 6.023 10²³ 96500 60 electrons & =3.74 10²⁰ electrons aligned
