How many atoms does o have
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.
