Question

What information is needed to calculate the average atomic mass of an element?(1 point) Responses  the charge on each isotope the charge on each isotope  the number of protons in each isotope the number of protons in each isotope  the relative abundance of its isotopes 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 **the mass of each isotope**. The charge on each isotope and the number of protons in each isotope are not directly needed for calculating average atomic mass. The total amount of the element in the sample or in nature is also not necessary for this calculation.

So, the correct response is: **the relative abundance of its isotopes**.
