WebThe 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. WebThese molar amounts are used to compute whole-number ratios that can be used to derive the empirical formula of the substance. Consider a sample of compound determined to contain 1.71 g C and 0.287 g H. The corresponding numbers of atoms (in moles) are: 1.71 g C × 1 mol C 12.01 g C = 0.142 mol C 0.287 g H × 1 mol H 1.008 g H = 0.284 mol H
