Question
(a) Combustion analysis of toluene, a common organic
solvent, gives 5.86 mg of CO2 and 1.37 mg of H2O. 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 C, H, and O. A
0.1005-g sample of menthol is combusted, producing 0.2829 g
of CO2 and 0.1159 g of H2O. What is the empirical formula
for menthol? If menthol has a molar mass of 156 g/mol,
what is its molecular formula?
