6. A volatilization gravimetry experiment was conducted on an unknown organic liquid (presumed to only contain carbon, hydrogen, and oxygen). The liquid was massed (data in the first column below) and then combusted in an excess of oxygen. The exhaust gas was passed through a trap containing drierite and then through a trap containing ascarite. The starting and ending masses of the drierite and ascarite were used to obtain the data in the second two columns below. Mass Unknown 12.4370 12.5590 12.2230 Mass CO2 17.0822 17.2497 16.7882 Mass H₂O 13.9849 14.1221 13.7443 A.) Calculate the mass percent of carbon, hydrogen, and oxygen in the unknown liquid. There are no outliers, so you can average the data before processing, if you wish. B.) Calculate the empirical formula of the unknown compound.
