A scientist decides to determine the molecular formula of a compound containing only carbon and hydrogen. The compound is first analyzed by combustion analysis. 2.257 g of the compound was found to produce 4.21 L of carbon dioxide gas at 1.0 bar, 298.15 K, and 1.92 g of water. Determine the empirical formula. The molecular formula is determined using data from the combustion analysis and the Dumas method. Given the Dumas method data below, determine the molecular formula of the...
