22 Οκτ 2024 · Learn how to calculate relative atomic mass for IGCSE Chemistry, using isotope mass numbers and abundance with worked examples.
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 (A r) or atomic weight. The atomic mass constant (symbol: mu) is one-twelfth of the mass of a carbon-12 atom.
The relative atomic mass of an element is an average value that takes account of the abundance of the isotopes of the element. Students should be able to calculate the relative atomic mass of an element given the percentage abundance of its isotopes.
The relative atomic mass of an element is a weighted average of the masses of the atoms of the isotopes – because if there is much more of one isotope then that will influence the average...
