Question

what is difference between relative atomic and relative mass?​

Answer 1

Answer:

Relative atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. Atomic mass is just the mass of atoms in an element BUT they are not necessarily the same mass so we get Chlorine as 35.453 u ± 0.002 u!

Answer 2

The sum of number of protons and neutrons of an atom is known as Relative Atomic Mass. Relative Molecular mass is defined as the ratio of the mass of 1 mole of that substance to one-twelfth the mass of one mole of C-12.
