Answer 1

To calculate the average atomic mass of an element, the correct information needed is:

**the relative abundance of its isotopes.**

This includes the mass of each isotope and how much of each isotope is present in a given sample, which allows for the weighted average to be computed. The other options provided are not necessary for this calculation.
