Correct Answer: C) The average mass of all atoms of an element relative to 1/12 of the mass of a carbon-12 atom, taking into account their natural isotopic abundances
Relative atomic mass is the weighted average mass of the atoms of an element compared with 1/12 of the mass of a carbon-12 atom. It has no unit.
