The unified atomic mass unit (u), or dalton (Da), or, sometimes, universal mass unit, is a unit of mass used to express atomic and molecular masses. It is defined as one-twelfth of the mass of an unbound atom of carbon-12 ( 12 C ) at rest and in its ground state.

Atomic Masses. The atomic mass of an element is the average mass of the atoms of an element measured in atomic mass unit (amu, also known as daltons, D). The atomic mass is a weighted average of all of the isotopes of that element, in which the mass of each isotope is multiplied by the abundance of that particular isotope.
