Yeah man I can help explain a little bit fits
Answer:
a. C > F > Cl
Explanation:
We know that atomic mass of Chlorine is greater than of Florine than that of carbon. Moreover, in CF2Cl2, therefore, there are two atoms of Cl, F and one atom of C. Therefore, in CF2Cl2 in order of decreasing mass percent composition C > F > Cl. Therefore, the correct option is a.
If 35Cl = 34.969 amu and 37Cl = 36.966 amu
Average atomic mass of the sample of chlorine..;
; [34.969(75.78) + 36.966(24.22)] ÷ 100....,where 100 is the total percentage.
; 3545.267 ÷ 100
; Hence the average atomic mass....,
35.453 amu
