Question

An ion is reduced to the element when it absorbs $6\times$ ${10}^{20}$ electrons. The number of equivalents of the ion is:

• A. $0.1$
• B. $0.01$
• C. $0.001$
• D. $0.0001$

Answer 1

The correct option is C $0.001$

1 equivalent of atom absorb $6.023\times {10}^{23}$ electrons.

So, no. of equivalent = $\frac{6\times {10}^{20}}{6\times {10}^{23}}=0.001$
