Question

Difine relacltive atomic mass?

Answer 1

Answer:

Relative atomic mass (symbol: Ar) 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 (symbol: mu) is defined as being 1/12 of the mass of a carbon-12 atom.Since both quantities in the ratio are masses, the resulting value is dimensionless; hence the value is said to be relative.

Answer 2

Explanation:

the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12.
