Which statements regarding combustion analysis to determinepercent composition are not correct?
ﾃつﾃつﾃつﾃつﾃつ I. The mass of oxygen in the samplecompound can be determined from the mass of carbon dioxide that isproduced.
ﾃつﾃつﾃつﾃつﾃつ II. If a compound contains anelement other than carbon and hydrogen, combustion analysis cannotbe used to determine its empirical formula.
ﾃつﾃつﾃつﾃつﾃつ III. Combustion analysis data aloneis not sufficient to determine the molecular formula withcertainty.
IV. If some CO is produced rather than all CO2, then theempirical formula that is calculated will be too high incarbon.
