Atomic Mass Calculator

Description and Uses

This Atomic Mass Calculator helps you determine the average atomic mass of an element based on the masses and relative abundances of its isotopes. It is commonly used in chemistry and physics to understand elemental properties and behavior in reactions.

Instructions

1. Input each isotope as mass:abundance%.
2. Separate multiple isotopes using commas.
3. Click "Calculate" to see the result.

Formula

Average Atomic Mass = (mass₁ × abundance₁ + mass₂ × abundance₂ + ... ) / 100
