The weight of silver (at.wt. = 108 ) displaced by a quantity of electricity which displaces 5600   m L of O 2 at STP will be

Options

  1. A5.4 g
  2. B10.8 g
  3. C54.0 g
  4. D108.0 g

Correct answer

D. 108.0 g

Step-by-step solution

n O 2 = 5600 22400 = 1 4 W A g 108 × 1 = W O 2 M O 2 × 4 2 H 2 O → O 2 + 4 H + + 4 e - W A g 108 = 1 4 × 4 W A g = 108 g
