C%Â Â Â Â Â =Â Â 12*wt of CO2*100/44*wt of organic compound

Â Â Â Â Â Â Â Â Â Â Â = 12*14.9*100/44*6.1Â Â = 66.62%

H%Â Â Â = 2*wt of H2O*100/18*wt of organic compound

Â Â Â Â Â Â Â Â Â = 2*6.1*100/18*6.1Â Â = 11.11%

O%Â Â Â Â Â = 100-(C% +H%)

Â Â Â Â Â Â Â Â Â Â Â = 100-(66.62+11.11)Â Â = 22.27%
