Question

A certain current liberated 0.504 g of hydrogen in 2
hours. How many grams of copper can be liberated
by the same current flowing for the same time in
copper sulphate solution​

Answer 1

Answer:Correct option (b) 16.0 g

Explanation:

Mass of Hydrogen/ Mass of copper                                                                                                         = Equivelent Mass of Hydrogen/Equivelent Mass of copper                                                 0.504/Mass of copper= 1/63.5/2                                                                                            Mass of copper deposited                                                                                                 = 16.0g
