To find the empirical formula, convert the percentages to moles:  - C: 49.32 g / 12.01 g/mol = 4.106 moles  - H: 6.85 g / 1.008 g/mol = 6.795 moles  - O: 43.84 g / 16.00 g/mol = 2.740 moles  Divide each by the smallest number of moles (2.740):  - C: 4.106 / 2.740 = 1.5  - H: 6.795 / 2.740 = 2.48  - O: 2.740 / 2.740 = 1  Multiply each by 2 to get whole numbers:  - C: 1.5 * 2 = 3  - H: 2.48 * 2 = 5  - O: 1 * 2 = 2  The empirical formula is C₃H₅O₂.
