Answer:
70.202 amu
Explanation:
From the question given above, the following data were obtained:
Isotope A:
Abundance (A%) = 39.9%
Mass of A = 69 amu
Isotope B:
Abundance (B%) = 60.1%
Mass of B = 71 amu
Average atomic mass =?
The average atomic mass of the element can be obtained as follow:
Average atomic mass = [(Mass of A × A%)/100] + (Mass of B × B%)/100]
= [(69 × 39.9)/100] + [(71 × 60.1)/100]
= 27.531 + 42.671
= 70.202 amu
Therefore, the average atomic mass of the element is 70.202 amu
