Element X has two natural isotopes: X-6 (6.015 amu) and X-7 (7.016 amu). Calculate the atomic mass of element X given the abundance of X-7 is 92.5%

The atomic mass of element X is 6.941 amu.

Explanation:

The atomic mass of the element X is given by:

We have that the abundance of X-7 is 92.5%, so the abundance of X-6 is:

Hence, the atomic mass of element X is:

Therefore, the atomic mass of element X is 6.941 amu.
