... The atomic mass of chlorine is 35.453. How was this calculated? There are two natural isotopes of chlorine, chlorine35 (17p+ and 18n) and chlorine 37 (17p+ and 20n) 35.453 is a weighted average because the percentage of Cl35 that is found in nature is 75.78% and percentage of Cl37 is 24.22% S ...
