To find the empirical formula, convert the mass of each element to moles by dividing by their atomic masses (C: 12 g/mol, H: 1 g/mol, O: 16 g/mol), resulting in C: 0.44 mol, H: 1.11 mol, O: 0.22 mol. Then, divide by the smallest number of moles (0.22 mol) to get the simplest whole number ratio: C: 2, H: 5, O: 1, which corresponds to the empirical formula C2H5O.
