Record number: 1, Textual support number: 1 DEF
[The] sum of the atomic weights of the elements of a chemical compound each multiplied by the number of atoms of that element in the molecule, [representing] the average mass of a molecule relative to the mass of the carbon isotope12C, which is assigned the value of exactly 12. 7, record 1, English, - relative%20molecular%20mass
Record number: 1, Textual support number: 1 OBS
Atomic weights (and therefore molecular weights) are relative weights arbitrarily referred to an assigned atomic weight of 12.0000 exactly for the most abundant isotope of carbon, C12. Prior to Sept. 8, 1960, natural oxygen, a mixture of isotopes, served as the standard of reference with an assigned atomic weight of 16.0000 exactly. 8, record 1, English, - relative%20molecular%20mass
