WebMar 31, 2024 · Find the chemical formula for the compound. This is the number of atoms in each element that makes up the compound. (This information is given in any chemistry reference book.) For example, the formula for hydrogen chloride (hydrochloric acid) is HCl; for glucose, it is C 6 H 12 O 6. 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.
