Let the percentage of isotope X-16 = x
The percentage of isotope X-18 = 100-x
Relative atomic mass = 16.2
Formula: Relative atomic mass =
Putting the value of parameter in above formula
16.2 = [16x + 18(100-x)] /100
The value of x is 90
Therefore percentage of isotope of mass no. 16 is 90%, while for isotope-18 is 10%
The percentage of isotope X-18 = 100-x
