Worked Solution & Example Answer:Define relative atomic mass. - Leaving Cert Chemistry - Question a - 2012
Step 1
Define relative atomic mass.
Answer
Relative atomic mass is defined as the average mass of the atoms of an element, measured relative to one-twelfth ( rac{1}{12}) of the mass of a carbon-12 atom.
In other words, it is a dimensionless quantity that provides a comparison of the mass of atoms of different elements against a standard reference. This concept allows chemists to understand the mass of elements in a standardized way, making it easier to calculate chemical reactions and molecular weights.
