The 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.

The chemical composition of bauxites is unstable: even within one deposit there are significant fluctuations in the contents of both the main components and the impurities [4]. It has been established that bauxites contain at least 42 chemical elements, these elements comprising the main body of ore and the associated impurities [2].

Solution. The H:C ratios for the two alcohols are 4:1 = 4.0 for methanol and 6:2 (3.0) for ethanol. Alternatively, one sometimes uses mole fractions to express the same thing. The mole fraction of an element M in a compound is just the number of atoms of M divided by the total number of atoms in the formula unit.
