Question

9.525 g of copper displaces 32.4 g of silver from a
solution of silver nitrate. Find the equivalent mass
of copper. (Equivalent mass of silver is 108.)​

Answer 1

Answer:

Correct option is

B

32

As 2.8g of iron displaces 3.2g of Cu from a solution of copper sulphate. Then the equivalent mass of copper can be determined as follows:

W = mass, E = equivalent mass.
