The ratio of the average mass of atoms of a chemical element in a given sample to the atomic mass constant is defined as relative atomic mass (Ar) or atomic ...

The relative formula mass (M r ) of a compound is calculated by adding together the relative atomic masses (A r ) of the atoms present in the compound.

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.

The relative atomic mass of an element is defined as the weight in grams of the number of atoms of the element contained in 12.00 g of carbon-12.
