Y Part B Menthol, the substance we can smell in mentholated cough drops, is composed of C. H. and O. A 0.1005-mg sample of menthol is combusted, producing 0.2829 mg of CO₂ and 0.1159 mg of H₂O. What Is the empirical formula for menthol? Express your answer as a chemical formula. C10H200 ✓ Previous Answers Correct Since both CO₂ and H₂O contain oxygen, there is an extra step to calculate the number of moles of oxygen in the sample. The numbers of moles of C and H calculated from the collected masses of CO₂ and H₂O, respectively, must be converted to the masses of C and H. Once you have the mass of each, the mass contribution of C and H can be subtracted from the mass of the menthol sample. This will give you the mass of oxygen, which can be converted to moles using its atomic mass. Part C If the compound has a molar mass of 156 g/mol, what is its molecular formula? Express your answer as a chemical formula. ΕΞΑΣΦΑ 4
