A certain current liberated 0.504 g of hydrogen in 2 h. How many grams of copper can be liberated by the same current flowing for the same time in a copper sulphate solution? Given Atomic mass of Cu = 63.5

Options

  1. A12.9 g
  2. B15.9 g
  3. C31.7 g
  4. D36.9 g

Correct answer

B. 15.9 g

Step-by-step solution

W e i g h t o f C u W e i g h t o f H 2 = E q . w t . o f C u E q . w t . o f H 2 Weightm of Cu 0.504 = 63.6/2 1 ∴ Weight of Cu = 15.9 g
