Use our Average Atomic Mass Calculator to accurately determine the average atomic mass of an element from its isotopes. Input each isotope's mass and its natural abundance to get immediate, precise results. Essential for chemistry students, researchers, and professionals.
Formula:
Average Atomic Mass = ∑ (Misotope × Aabundance)
Where:
• Misotope = Mass of a specific isotope (e.g., in atomic mass units, amu)
• Aabundance = Natural abundance of that isotope (as a decimal fraction or percentage, e.g., 0.75 or 75%)
