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 "=36.9659`
`therefore" Average atomic mass "=(0.7577)+(34.9689 amu)+(0.2423)(36.9659amu)`
`=26.4959+8.9568= 34.4527`
