Calculating Average Atomic Mass
Part of understanding isotopes is realizing how their abundance determines the average atomic mass shown with each element of the periodic table. This worksheet will show students how these numbers are calculated, and help them understand why the atomic mass of oxygen is 15.99 AMU instead of simply 16 AMU.
Essential Concepts: Isotopes, average atomic mass, isotope abundance, atomic mass units.
