**Combustion Analysis of an Organic Compound** A 7.478 gram sample of an organic compound containing carbon (C), hydrogen (H), and oxygen (O) is analyzed through combustion analysis. The process produces 19.34 grams of carbon dioxide (CO₂) and 3.959 grams of water (H₂O). In a separate experiment, the molar mass is determined to be 136.2 g/mol. Use this information to determine the empirical formula and the molecular formula of the organic compound. **Enter the elements in the order C, H, O:** - Empirical formula = [____] - Molecular formula = [____] --- **Diagram Explanation:** The diagram depicted is a combustion analysis apparatus. It includes: - **Furnace:** The main unit where the sample is heated. - **Sample (labelled):** The organic compound under analysis. - **H₂O Absorber:** A unit that captures the water produced during combustion. - **CO₂ Absorber:** A unit that captures the carbon dioxide produced during combustion. These components work together to analyze the combustion of an organic compound, allowing for the measurement of CO₂ and H₂O produced, which are critical for determining the composition of the compound.
