For example, the atomic weight of the element chlorine is 35.453, determined by averaging the atomic masses and relative abundances of its two main naturally occurring isotopes, which have atomic masses of about 35 and 37.
Atomic Weight Calculation Example. If chlorine has two naturally-occurring isotopes where: Cl-35 mass is 34.968852 and fract is 0.7577. Cl-37 mass is 36.965303 and fract is 0.2423. atomic weight = massa x fracta + massb x fracb. atomic weight = 34.968852 x 0.7577 + 36.965303 x 0.2423. atomic weight = 26.496 amu + 8.9566 amu.
