SUMMARY
Molar mass is defined as the mass of one mole of atoms of an element, while relative mass is the average mass of one atom of that element compared to 1/12 of the mass of a carbon-12 atom. The relationship between these two concepts is established through the definition of a mole, which is designed to ensure that the numerical value of molar mass in grams per mole is numerically equal to the relative atomic mass. This equivalence allows for straightforward conversions between atomic scale measurements and macroscopic quantities.
