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

Some Basic Concepts of Chemistry

Solution:

$6 \times 10^{23}$ electrons = 1 equivalent
$\therefore 6 \times10^{20}$ electrons $=\frac{6\times10^{20}}{6\times10^{23}}=0.001$ equivalent
