This technical article explains the confusion resulting from molecular weight and the nominal mass, monoisotopic mass and average molar mass.
Mass associated with chemical formulae is different for those working in mass spectrometry as compared to those working in other fields of chemistry and in physics. Very early in science training, students are introduced to units of mass on the atomic scale. These units of mass are called atomic weights or atomic masses.
