5.

5. In words, describe how to find an average.

Asemmisa {{asɛmmisaAhyɛnsode}}

8.

Calculate the percent abundance of isotope #1. To do this, divide the total number of atoms for
isotope #1 by the total number of atoms of all isotopes. Multiply by 100 to get a percent. Show all
work.

Calculate the percent abundance of isotope #2. Show all work.

Asemmisa {{asɛmmisaAhyɛnsode}}

10.

Calculate the percent abundance of isotope #3. Show all work.

Asemmisa {{asɛmmisaAhyɛnsode}}

11.

Based on the percent abundance, which isotope is most abundant? Explain.

12.

Why isn’t the atomic mass of most of the elements on the Periodic Table a whole number?

Asemmisa {{asɛmmisaAhyɛnsode}}

13.

Which number in the data chart is the average atomic mass for the element Beanium? Show the calculation you used to figure out the answer.
