Final Answer:
The most likely average atomic mass for Element X is 10.1 amu, indicating a predominant isotope with this mass.
Explanation:
The atomic mass of an element is the weighted average of the masses of all its naturally occurring isotopes. Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons, resulting in different atomic masses.
If the most likely average atomic mass for Element X is 10.1 amu, it suggests that there are multiple isotopes of Element X, each with a different atomic mass. Among these isotopes, the one with an atomic mass of approximately 10.1 amu is the most abundant or frequently occurring. This isotope's abundance plays a significant role in determining the element's average atomic mass.
Scientists use various analytical techniques, such as mass spectrometry, to determine the relative abundances of isotopes and their corresponding atomic masses accurately.
