| atomic mass |
the mass of an atom relative to the mass of carbon-12, 12 C (=12.000), eg, the atomic mass of 1 H is 1.007825, although it is generally good enough to approximate it as simply 1.000. Similarly, the molecular mass is the mass of a molecule relative to 12 C, eg, the molecular mass of methane (CH 4 ) is 12 + 4 x 1.000 = 16 (assuming that all the hydrogen is present as 1 H.

| atomic mass |
the cumulative average of the following: the average of the mass numbers of all the isotopes of that element with their natural abundances factored in, along with mass defect and the understanding that the number 1 (1 u) is a comparison to 1/12 of the mass of a carbon-12 atom.

| atomic mass |
The mass of a neutral atom of a nuclide. The atomic weight of an atom is the weight of the atom based on a scale where 12C = 12. The atomic weight of an element is the weighted average of each isotope.
