Question

What information is needed to calculate the average atomic mass of an element? (1 point)

the number of protons in each isotope

the charge on each isotope

the relative abundance of its isotopes

the total amount of the element in the sample or in nature

Answer 1

To calculate the average atomic mass of an element, you need **the relative abundance of its isotopes** and their corresponding atomic masses. The number of protons, charge, and total amount of the element are not necessary for this specific calculation.
