<u>Answer:</u> The percentage abundance of and
isotopes are 75.77% and 24.23% respectively.
<u>Explanation:</u>
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
.....(1)
Let the fractional abundance of isotope be 'x'. So, fractional abundance of
isotope will be '1 - x'
- <u>For
isotope:</u>
Mass of isotope = 34.9689 amu
Fractional abundance of isotope = x
- <u>For
isotope:</u>
Mass of isotope = 36.9659 amu
Fractional abundance of isotope = 1 - x
- Average atomic mass of chlorine = 35.4527 amu
Putting values in equation 1, we get:
Percentage abundance of isotope =
Percentage abundance of isotope =
Hence, the percentage abundance of and
isotopes are 75.77% and 24.23% respectively.
