The average atomic mass formula is:
[tex]average atomic mass = \Sigma (percent abundane)\times (atomic mass)[/tex]
Substituting the values in the formula:
[tex]average atomic mass = \frac{78.99\times 23.9850+10\times 24.9858+11.01\times 25.9826}{100}[/tex]
[tex]average atomic mass = \frac{1894.57515+249.858+286.068426}{100}[/tex]
[tex]average atomic mass = 24.30516 amu[/tex]
Hence, [tex]24.30516 amu[/tex] is the average atomic mass of element M.
The average atomic mass (in amu) of element M is 24.30516 amu.
How we calculate the average atomic mass of any element?
The average atomic mass of any element will be calculated by adding the product of the atomic mass of that element and relative abundance percent of isotope of that element.
Given atomic mass (amu) of element M = 23.9850, 24.9858, 25.9826
Given relative abundance % respectively = 78.99, 10.00, 11.01
Putting all these values on the calculation of the average atomic mass of element M as:
Average atomic mass = (23.9850×78.99)+(24.9858×10)+(25.9826×11.01)/100 Average atomic mass = 24.30516 amu
Hence, 24.30516 amu is the average atomic mass of element M.
