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 `=(1 xx 98.985 + 2 xx 0.015)/(99.985 + 0.015)`
= 1.00015 u.
