Neon is naturally available as `""^(20)Ne and ""^(22)Ne` with average atomic mass 20.2. Calculate the relative abundance of heavier isotope.

Text Solution

Verified by Experts

Let the percentage abundance of `""^(22)Ne` is x. The percentage abundance of `""^(20)Ne` is `100-x`.
`20.2=((100-x)20+22x)/(100)`
`"Percent abundance of "^(20)Ne=10%`
