Question

When 3.006 grams of a hydrocarbon, CxHy, were burned in a combustion analysis apparatus, 10.16 grams of CO2 and 2.080 grams of H2O were produced. In a separate experiment, the molar mass of the compound was found to be 78.11 g/mol. Determine the empirical formula and the molecular formula of the hydrocarbon. Enter the elements in the order presented in the question. empirical formula = molecular formula =

Step 1

First, we need to find the moles of CO₂ and H₂O produced in the reaction. Moles of CO₂ = mass of CO₂ / molar mass of CO₂ Moles of CO₂ = 10.16 g / (12.01 g/mol + 2 * 16.00 g/mol) Moles of CO₂ = 10.16 g / 44.01 g/mol Moles of CO₂ = 0.2309 mol Moles of H₂O = mass Show more…
