Answer: It shows that the majority of isotopes have a mass number of 1 over 2 or 3.
Explanation:
The average atomic mass is calculated by summing the masses of each isotope weighted by their relative abundances.
The formula applied is:
Given three hydrogen isotopes: H-1, H-2, and H-3.
The average atomic mass is 1.00794 amu.
This value being very close to the mass of H-1 indicates its natural abundance is much greater than those of H-2 and H-3.
The abundance of H-1 is approximately 99.98%.
The combined abundances of H-2 and H-3 are about 0.02%.
Therefore, this data implies that isotopes with mass 1 are more numerous than those with masses 2 or 3.
