WebRelative atomic mass can be calculated by multiplying the isotope abundance times the isotope mass for each isotope of that element and adding the resulting values. To simplify the calculations, the mass number of an isotope is often used in place of the mass. Relative atomic mass (symbol: Ar; sometimes abbreviated RAM or r.a.m.), also known by the deprecated synonym 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 va…
