Fructose's empirical formula can be determined by converting the percent composition to grams (assuming 100g of substance), then to moles, and finally to the simplest whole number ratio. For 40.00% C, 6.72% H, and 53.29% O, the moles are calculated as follows: C: 40.00g / 12.01g/mol = 3.33 moles, H: 6.72g / 1.008g/mol = 6.67 moles, O: 53.29g / 16.00g/mol = 3.33 moles. The simplest whole number ratio is approximately 1:2:1, which corresponds to the empirical formula CH₂O.
