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. The atomic mass of an atom is a feature that is closely related to its mass number. A single atom’s atomic mass is just its total mass, and it is commonly given in atomic mass units or amu. Carbon-12, an atom of carbon-containing six neutrons, has an atomic mass of 12 amu. Other atoms typically do not have round-number atomic masses. The average mass is the relative atomic mass, which can be easily calculated from the percentage composition ( % abundance).
