Calculate the average atomic mass of hydrogen using the following data
Isotope % Natural abundance Molar mass
`.^(1)H 99.985 1`
`.^(2)H 0.015 2`

Text Solution

Verified by Experts

Average Atomic Mass
`({("Natural abundance of ".^(1)H xx "molar mass")+("Natural abundance of ".^(2)H xx " molar mass of ".^(2)H)})/(100) = (99.985 xx 1 + 0.015 xx 2)/(100)`
`= (99.985 + 0.030)/(100) = (100.015)/(100) = 1.00015 u`
