Question

(a) Chlorine occurs in nature in two isotopic form with masses 35 u and 37 u
in the ratio of 3 : 1. Calculate average atomic mass of chlorine atom on the
basis of their data?
​

Answer 1

Two Isotopes of chlorine are in ratio 3 : 1 that means they are 75% and 25% respectively.

Average atomic mass of chlorine

=

$\frac{35 \times 75}{100} + \frac{37 \times 25}{100}$

=

$\frac{105}{4} + \frac{37}{4}$

=

$\frac{142}{4}$

= 35.5 u

Average atomic mass of chlorine atom = 35.5 u
