Given that the percentage abundance of the isotope `._(10)^(20)N` is 90 % and that of the isotope `._(10)^(22)Ne` is 10 %, calculate the average atomic mass of neon.

Text Solution

Verified by Experts

Isotope `""_(10)^(20)Ne = `90%. Isotope `""_(10)^(20)Ne` = 10%
Average atomic mass of neon `= (20 xx 90 +22 xx 10)/(100) = 20.2 u`
