Answer:
d. 114.8 u
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
<u>For first isotope:
</u>
% = 95.72 %
Mass = 114.9041 u
<u>
For second isotope:
</u>
Since the element has only 2 isotopes, so the percentage of second is 100 - first percentage.
% = 100 % - 95.72 % = 4.28 %
Mass = 112.9043 u
Average Mass = ?
Thus,
<u>Average atomic mass = 114.8 u</u>
