Sir relative atomic mass is same as average atomic mass?

[@UmairKhanAcademy]

1. Average atomic mass is 'average of all relative atomic masses' in case of different isotopes and their different abundance. 2. Both may be considered same in case of single isotope. 3. Both are really comparative because they belong to same element. 4. In case of different isotopes, if one isotope's abundance is more than 99%, then both relative and average atomic mass values are very near or almost same. (i.e. hydrogen)

@UmairKhanAcademy ok sir
