A certain compound contains 8.74% Carbon, 13.8% Fluorine, 77.4% Chlorine by weight. A possible molecular formula for this compound might be? I think the answer is CF2Cl26 multipy mass of each element by the percent: c: 12.01*.0874=1.049674 F: 19*.138=2.62...

So: C=.7277 F=.7263 Cl=2.183 then C=1 F=0.99 Cl=2.9998 so wouldn't Cl round up to 3? CFCl3

Thank you!
