Relative atomic mass in unitless.why?
Answers
Answer:
Why are atomic masses unitless? It is because they are relative masses where the mass of one atom is compared to the other. ... If we could find the mass of the same sized bunch of atoms of two different kinds, say Hydrogen and Oxygen, then we could compare their masses.

=>It is because they are relative masses where the mass of one atom is compared to the other. ... If we could find the mass of the same sized bunch of atoms of two different kinds, say Hydrogen and Oxygen, then we could compare their masses...
=>So, as you can tell, as long as Avogadro's hypothesis is true, we can choose an atom of any element to be our standard. So clearly, the atomic masses on the periodic table have no units attached to them because they are not actual masses, but relative atomic masses...
