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 of hydrogen `= (("Natural abundance of" .^(1)"H" xx"atomic mass")+("Natural abundance of".^(2)"H"xx"atomis mass of".^(2)H))/(100)`
`= (99.985xx1+0.015xx2)/(100)`
`=(99.985+0.030)/(100)=(100.015)/(100)=1.00015u`.
