Calculate the average atomic mass of hyd...

Calculate the average atomic mass of hydrogen using the following data :
`{:("Isotope","% Natural abudance mass","Atomic mass(amu)"),(.^(1)H," "99.985," "1),(.^(2)H," "0.015," "2):}`

Text Solution

Verified by Experts

`"Average atomic mass "= (Sigmap_(i)A_(i))/(100)" "(p_(i)="percent abundance, "A_(i)="atomic mass of isotope ")`
`=(99.985xx1+0.015xx2)/(100)=(99.985+0.030)/(100)=(100.015)/(100)=1.00015u.`
