wherempis the mass of aprotonandmnis that of a neutron, the difference,AM, is called themass defect, as it reflects the deficiency in mass between the mass of the individual constitutes of the nucleus and its collective mass. The energy corresponding to ΔM, according toEq. (1.1), isB= ...
This is defined as “the average mass of the molecule divided by 1/12 of the mass of an atom of the nucleide C12.” The older term molecular weight is still widely used by polymer technologists. Frequently, quoted molecular weights are dimensionless, but again can be quoted in kg mol−...
but by the quantity of each type of atom or ion. For example, water, H2O, and hydrogen peroxide, H2O2, are alike in that their respective molecules are composed of hydrogen and oxygen atoms. However, because a hydrogen peroxide molecule contains two oxygen atoms, as opposed to the...

Mass spectrometry is a standard technique for the analytical investigation of molecules and complex mixtures. It is important in determining the elemental composition of a molecule and in gaining partial structural insights using mass spectral fragmentations. The final structure confirmation of an unknown...
