Average Atomic Mass Calculator

Calculate the Average Atomic Mass of an Element

Isotope 1 Mass (amu): Isotope 1 Abundance (%): Isotope 2 Mass (amu): Isotope 2 Abundance (%): Isotope 3 Mass (amu) (Optional): Isotope 3 Abundance (%) (Optional):

Note: The sum of all isotope abundances must equal 100%.

Average Atomic Mass = Σ(Mass × Abundance / 100)
