No difference whatsoever. In fact the term "atomic mass" is the more
accurate, given that the units are grams per mole, and mass is the one
which is measured in grams. (weight is a force and is measured in Newtons,
but the units for atomic "weight" are still grams per mole!).
You will
find the term atomic weight used more often in older books.
If you're
wondering what a mole is, its a number for comparing quantities of
particles. A bit like dozen but very very much bigger.
