An element have two isotopes with mass number 16 and 18.The average atomic weight is 16.5.The percentage abundance of these isotopes are _______and____________respectively.
75,25
Assume % abundance of the element with atomic number16 is 'a' then % abundance of the element with atomic number18 is 100-'a' in nature.
The average atomic mass of element "X" will be.
% abundance of the element with atomic number16 is '75' then % abundance of the element with atomic number18 is 100-'75'=25 in nature.
Conclusion Statement: Option (a) is the correct answer.
