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 relative atomic mass of an element is a weighted mean mass of the isotopes of an element compared with that of the 12C isotope, which has a mass of exactly ...

16 апр. 2024 г. · A more common definition of relative atomic mass is the mass of an atom compared to 1/12th of the mass of a carbon-12 atom.

The relative atomic masses of elements are proportional measures. For example, the Ar for carbon is 12, and the Ar for magnesium is 24. This means that ...

The relative atomic mass of an element is the weighted mean mass of its atoms compared to 1⁄12th the mass of a 12C atom. It is given the symbol Ar.

Relative atomic mass (A r ) is the weighted average mass of one atom of each element – compared to 1/12 the mass of one atom of carbon-12.

Relative atomic mass (A r ) is the average mass of an element compared to one-twelfth the mass of a single carbon-12 atom.

Relative atomic mass can be defined as the ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant.

A relative atomic mass (also called atomic weight; symbol: A r ) is a measure of how heavy atoms are. It is the ratio of the average mass per atom of an element

The relative molecular mass of a molecule is the average mass of one molecule of that element or compound compared to 1/12 of the mass of one carbon-12 atom.
