Relative Molecular Mass Calculations Chemistry Tutorial

Relative molecular mass of a compound (M r) is defined as the mass of a formula unit of the compound relative to the mass of a carbon atom taken as exactly 12. In practice, the relative molecular mass of a compound, M r , is the sum of the relative atomic masses ( atomic weights ) of the atomic species as given in the chemical formula .

Relative atomic mass - Wikipedia

Relative atomic mass (syol: A r) or atomic weight is a dimensionless physical quantity defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant.The atomic mass constant (syol: m u) is defined as being 1 / 12 of the mass of a carbon-12 atom…

Mass (mass spectrometry) - Wikipedia

Isotope abundances are tabulated by IUPAC: for example carbon has two stable isotopes 12 C at 98.9% natural abundance and 13 C at 1.1% natural abundance, thus the nominal mass of carbon is 12. The nominal mass is not always the lowest mass nuer, for example iron has isotopes 54 Fe, 56 Fe, 57 Fe, and 58 Fe with abundances 6%, 92%, 10%, and 2%, respectively, and a nominal mass of 56 Da.
