Hey mate...!! ☺☺
Relative atomic mass is a dimensionless (number only) physical quantity.
The mass of atoms can vary (between atoms of the same element), due to the presence of various isotopes of that element. Since both values in the ratio are expressed in the same unit (u), the resulting value is dimensionless; hence the value is relative. The older term atomic weight is exactly equivalent, and still much in use
The atomic mass is the mass of an atom. It is commonly expressed in unified atomic mass units where by international agreement, 1 unified atomic mass unit is defined as 1⁄12 of the mass of a single carbon-12 atom (at rest). For atoms, the protons and neutrons of the nucleus account for almost all of the mass, and the atomic mass measured in u has nearly the same value as the mass numbers..
