If,105.5mg sample of a white substance, suspected of being cocaine (C17H21NO4), forms 279.3mg of CO2 and 66.46mg of water on combustion, then we can conclude that the white solid is cocaine.

Thus from the above conclusion we can say that, If,105.5mg sample of a white substance, suspected of being cocaine (C17H21NO4), forms 279.3mg of CO2 and 66.46mg of water on combustion, then we can conclude that the white solid is cocaine.
