Question

what is actually the difference between relative atomic mass of an atom and atomic mass ? Is there any difference at all in terms of calculating the masses ?

Answer 1

You can approximate the atomic mass of a single isotope (not the element in general) by guessing that the atomic mass in atomic mass units is numerically the same as the mass number (the number of protons + the number of neutrons). However, that is only an approximation.
