Question

2.8 gram of iron displaces 3.2 gram of copper from a solution of copper sulphate solution is the equivalent mass of iron is 28 then equivalent mass of copper will be ​

Answer 1

Explanation:

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.

WCuECu=WFeEFe=3.2ECu=2.828

3.2ECu=2.828=0.1

So, 3.2ECu=0.1

ECu=3.20.1=32

So, equivalent weight of Cu is 32.

Answer 2

Explanation:

2.8 + 3.2 = 6.0 - 28 = 32 is this answer
