The weight of silver (at wt. = 108 ) displaced by a quantity of electricity which displaces 560 mL of O 2 at STP will be (Volume of 1 mole of gas at STP is 22.4 L)

Options

  1. A54.9 g
  2. B5.4 g
  3. C10.8 g
  4. D108.0 g

Correct answer

C. 10.8 g

Step-by-step solution

According to faraday's 2nd law w A g E A g = w O 2 E O 2 w A g 108 = 560 22400 × 32 8 ∴ w A g = 10.8 g
