WebbThe ratio of atoms is 2:4:2. Dividing by the lowest common denominator (2) gives the simplest, whole-number ratio of atoms, 1:2:1, so the empirical formula is CH 2 O. Note that a molecular formula is always a whole-number multiple of an empirical formula. Figure 2.21 (a) Vinegar contains acetic acid, C2H4O2, which has an empirical formula of CH2O. WebbFinal answer Step 1/3 (a) To determine the empirical formula, we need to find the smallest whole-number ratio of the elements. Divide each value by the smallest value to get the mole ratio: C: 0.0091 mol / 0.0045 mol = 2.02 H: 0.0186 mol / 0.0045 mol = 4.13 O: 0.0045 mol / 0.0045 mol = 1.00
