If a certain amount of current liberated 0.504 g of hydrogen in 2 hours. Calculate the mass of copper liberated by the same current flowing for the same time in a copper sulphate solution

Options

  1. A12.7 g
  2. B15.9 g
  3. C31.8 g
  4. D63.5 g

Correct answer

B. 15.9 g

Step-by-step solution

Weight   of   Cu Weight   of   H 2   =   Eq .   weight   of   Cu Eq .   weight   of   H Weight   of   Cu 0.50 = 63.6 / 2 1 Weight   of   Cu   =   15 .9   g
