Define relative atomic mass class 11
WebCarbon is taken as the standard atom and has a relative atomic mass (A r) of 12. Atoms with an A r of less than this have a smaller mass than a carbon atom. WebApr 6, 2024 · A dimensionless physical quantity known as relative atomic mass (symbol: Ar) or atomic weight is defined as the ratio of the average mass of atoms of a chemical element in a particular sample to the atomic mass constant. The definition of the atomic mass constant (symbol: mu) is $\dfrac {1} {12}^ {th}$ of the mass of an atom of carbon-12.
