Component of citrus fruits is the bitter compound limonin, which contains only carbon, hydrogen, and oxygen. When a 1.000-gram sample of limonin is subjected to complete combustion, 2.432 grams of CO2 and 0.574 grams of H2O are produced. In addition, the molar mass of limonin is approximately 475 g/mol. Detrmine the emprirical formula and molecular formula of limonin.
