Question

When writing relative atomic mass, are there SI units to write like g/mol or something

Answer 1

Answer:

Relative atomic mass is a dimensionless quantity. It is relative mass of a species with respect to the mass of carbon-12. So the units of masses get cancelled and hence we have a 'unitless' quantity. Just like refractive index doesn't have a unit.

Answer 2

Explanation:

atomic relative mass is unitless because it is just the relation between the mass of any atom with the respect of the mass of c 12 atom
