Sodium exists in two isotopic forms

{Na}^{23}

and

{Na}^{24}

in nature. If

{Na}^{24}

is present at the abundance of

25 \%

in the nature. The average atomic mass of the element is :-

View answer and explanation

Correct option: C

23.25

Option C (23.25) is correct because it is the average atomic mass calculated considering the isotopic abundance.
