Answer:
Average atomic mass = 55.83 amu
Explanation:
The formula for the calculation of the average atomic mass is:
Given that:
For first isotope, Fe-54:
% = 6 %
Mass = 53.94 amu
For second isotope, Fe-56:
% = 92 %
Mass = 55.93 amu
For third isotope, Fe-57:
% = 2 %
Mass = 56.94 amu
Thus,
<u>Average atomic mass = 55.83 amu</u>
