Sagot :
Average atomic mass = f1M1 + f2M2 +… + fnMn
where f is the fraction representing the natural abundance of the isotope and M is the mass number (weight) of the isotope.
let x be the fraction of ^6li ,
then fraction abundance of [tex]^7li[/tex] will be (1-x)
now applying above equation:
6.941 = x × 6.0151 +(1-x) 7.0160
1.0009x = 0.075
x = 0.0749
so % of [tex]^6li[/tex]= 7.49%
% of [tex]^7li[/tex]= 92.50%
- Average Atomic Mass is the average mass of an element based on the percent abundance of each isotope of that element. (atoms with different number of neutrons, but same number of protons).
