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

Neon is naturally available as ""^(20)Ne and ""^(22)Ne with average at

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