What is the difference between unified mass and atomic mass unoy?

Answer 1

Answer: Atomic mass of an element expressed in grams is called gram atomic mass. Atomic mass unit (a.m.u) is the quantity of mass equal to 1/12th of the mass of an atom of carbon (C-12). ... Hence, the reference was changed to C-12 and a new symbol 'u' (unified mass) replaced the old symbol 'a.m.u'.
