Calculate the atomic mass (average) of chlorine using the following data:
`{:(,,"% natural abundance",,"Molar mass"),(.^(35)Cl,,75.77,,34.9689),(.^(37)Cl,,24.23,,36.9659):}`

Text Solution

Verified by Experts

Fractional abundance of `.^(35)Cl = 0.7577`, Molar mass = 34.9689
Fractional abundance of `.^(37)Cl = 0.2423`, Molar mass = 36.9659Average atomic mass = (0.7577) (34.9689 amu) + (0.2423) (36.9659 amu)
= 26.4959 + 8.9568 = 35.4527
