(a) Combustion analysis of toluene, a common organic solvent, gives $5.86 \mathrm{mg}$ of $\mathrm{CO}_{2}$ and $1.37 \mathrm{mg}$ of $\mathrm{H}_{2} \mathrm{O}$. If the compound contains only carbon and hydrogen, what is its empirical formula? (b) Menthol, the substance we can smell in mentholated cough drops, is composed of $\mathrm{C}, \mathrm{H},$ and $\mathrm{O} . \mathrm{A}$ 0.1005-g sample of menthol is combusted, producing $0.2829 \mathrm{~g}$ of $\mathrm{CO}_{2}$ and $0.1159 \mathrm{~g}$ of $\mathrm{H}_{2} \mathrm{O}$. What is the empirical formula for menthol? If menthol has a molar mass of $156 \mathrm{~g} / \mathrm{mol}$, what is its molecular formula?
