Therefore the molecular formula is twice the empirical formula: C2H6O2. The compound dioxane contains only carbon, hydrogen, and oxygen. When 0.956 g dioxane is burned, 1.91 g carbon dioxide and 0.782 g water are formed. In another experiment, it was determined that 6.04x10-3 mol dioxane weighs 0.532 g.

A carbohydrate () is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula Cm(H2O)n (where m may be different from n). This formula holds true for monosaccharides.

The simplest ketone is CH₃—C(=O)—CH₃. Its molecular formula is C₃H₆O. From this formula we can say that for “n” carbon atoms we need “2n” hydrogen atoms and an oxygen atom. Hence general formula of ketone is CnH₂nO.
