Which statements regarding combustion analysis to determine percent composition are not correct? I. The mass of oxygen in the sample compound can be determined from the mass of carbon dioxide that is produced. II. If a compound contains an element other than carbon and hydrogen, combustion analysis cannot be used to determine its empirical formula. III. Combustion analysis data alone is not sufficient to determine the molecular formula with certainty. IV. If some CO is produced rather...
