### Determining the Empirical and Molecular Formulas of an Organic CompoundIn this exercise, you will learn how to determine the empirical and molecular formulas of an organic compound through combustion analysis.#### Experimental Data:- **Mass of the organic compound sample:** 8.074 grams- **Mass of CO₂ produced:** 20.88 grams- **Mass of H₂O produced:** 4.274 grams- **Molar mass of the compound:** 136.2 g/mol#### Diagram Description:The diagram visualizes the combustion analysis process. It shows a container labeled “Sample” in which the organic compound is presumably combusted, leading to the production of CO₂ and H₂O. #### Objectives:Using the given data, calculate:1. The **empirical formula** of the organic compound.2. The **molecular formula** of the organic compound.#### Steps for Determining Formulas:1. **Calculate moles of C and H from combustion products:** - **Carbon (C):** Each mole of CO₂ contains 1 mole of Carbon. - Moles of CO₂ = 20.88 grams / 44.01 g/mol - Moles of C = Moles of CO₂ - **Hydrogen (H):** Each mole of H₂O contains 2 moles of Hydrogen. - Moles of H₂O = 4.274 grams / 18.02 g/mol - Moles of H = 2 × Moles of H₂O2. **Determine the mass of O in the compound sample:** - **Oxygen (O):** Use the difference in mass to find the remainder which is the mass of Oxygen. - Mass of O = Mass of sample - (mass of C + mass of H)3. **Convert masses to moles using their respective molar masses:** - Moles of O = (Mass of O) / 16.00 g/mol4. **Find the simplest whole number ratio of moles of C, H, and O to determine the empirical formula.**5. **Determine the molecular formula:** - Using the empirical formula, calculate the empirical formula molar mass. - Divide the given molar mass of the compound by the empirical formula molar mass to find the ratio. - Apply this ratio to the empirical formula to obtain the
