## What is the average atomic mass of an element?

The average atomic mass (sometimes called atomic weight) of an element is **the weighted average mass of the atoms in a naturally occurring sample of the element**. Average masses are generally expressed in unified atomic mass units (u), where 1 u is equal to exactly one-twelfth the mass of a neutral atom of carbon-12.
