4. A combustion device can be used to analyze organic compounds. Given that a certain amount of a compound containing carbon, hydrogen, and oxygen is combusted in this device, explain how the data relating to the mass of CO2 produced and the mass of H2O produced can be manipulated to determine the empirical formula.

Step 1
Combustion of the organic compound produces CO_2 and H_2O. The balanced chemical equation can be represented as: $$CxHyOz + \frac{x + \frac{y}{4} - \frac{z}{2}}{O_2} \rightarrow xCO_2 + \frac{y}{2}H_2O$$ Show more…

Combustion analysis of a $1.000$ -gram sample of a compound known to contain only carbon, hydrogen, and oxygen produces $1.500$ grams of $\mathrm{CO}_{2}(g)$ and $0.409$ grams of $\mathrm{H}_{2} \mathrm{O}(g)$. Determine the empirical formula of the compound.
A compound is known to contain carbon and hydrogen and might also contain oxygen. A sample is burned yielding $54.6 \% \mathrm{C}$ and $9.16 \% \mathrm{H}$. (a) What is the empirical formula of the compound? (b) The molar mass of the compound is $132.159 \mathrm{~g} / \mathrm{mol}$. What is the molecular formula? (c) Write the balanced combustion reaction (reaction with $\mathrm{O}_{2}$ ) for the compound.

Combustion Analysis
To use combustion analysis to find the empirical formula of an unknown hydrocarbon compound (containing only hydrogen and carbon), what specific data are needed? Select all that apply: The mass of CO2 collected. The mass of H2O collected. The mass of O2 used in the combustion. The mass of the sample.
