Question

11. The average atomic mass of a sample of an element X is 16.2 u.
What are the percentages of isotopes
16
8X and
$\frac{18}{8} x \: in \: the \: sample$?​

Answer 1

Answer:

Thus, the percentage of isotope 8 16 X will be (100 − y)%. Therefore, the percentage of isotope 8 18 X is 10%. And, the percentage of isotope 8 16 X is (100 − 10) % = 90%.
