Question

an Ion is reduced to the element when it absorbs 6 × 10 ^20 electrons the number of equivalents of the iron is

Answer 1

Here it is given that;

absorbed electrons by ion= 6.02*10^20

Weknow no. of electron in an element = 1 mole = 6.02*10^23

Now,

Eq. Of ion = 6.02*10^20 / 6.02*10^23

You will get; 10^-3

i.e. 0.001.
