When 4.079 grams of a hydrocarbon, CxHy, were burned in a combustion analysis apparatus, 11.94 grams of CO₂ and 7.333 grams of H₂O were produced. In a separate experiment, the molar mass of the compound was found to be 30.07 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 = A 2.143 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 4.872 grams of CO₂ and 1.995 grams of H₂O are produced. In a separate experiment, the molar mass is found to be 116.2 g/mol. 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: A 6.003 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 12.93 grams of CO₂ and 5.296 grams of H₂O are produced. In a separate experiment, the molar mass is found to be 102.1 g/mol. 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:
