Chem isotope
WebIn this worksheet, we will practice calculating percentage isotopic abundances from the relative atomic mass and isotopic masses. Q1: Chlorine has two stable isotopes, 3 5 C l and 3 7 C l , with atomic masses 34.9689 u and 36.9659 u respectively. The relative abundance of 3 7 C l in an average sample of chlorine is 3 7 3 5 C l C l = 0. 3 1 9 6.
