The exact term of the above molecular weight is "molar mass", which is based on the atomic mass of each element. Molecular weight is actually an older term of "relative molar mass" or "molecular mass", which is a dimensionless quantity equal to the molar mass divided by the molar mass constant defined by 1 g/mol.
