WebAug 15, 2024 · Working out the relative atomic mass. The relative atomic mass (RAM) of an element is given the symbol A r and is defined as:. The relative atomic mass of an element is the weighted average of the masses of the isotopes on a scale on which a carbon-12 atom has a mass of exactly 12 units A "weighted average" allows for the fact … WebRelative Atomic Mass (GCSE Chemistry) What is Relative Atomic Mass (RAM)?. The relative atomic mass (Ar) is the average mass of atoms of an element relative to the mass of an atom of carbon-12 (which is given a mass exactly of 12). The average mass must take into account the proportions of naturally occurring isotopes of the element.

WebRelative Atomic Mass can be written as RAM or A r. In a naturally occurring sample of Chlorine, 75% of the atoms will have a mass number of 35, 25% will have a mass number of 37. The average mass number for the sample will be [(75 x 35) + (25 x 37)] ÷100 = … 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…
