Chemical Formula from Empirical Formula. The chemical formula for a compound obtained by composition analysis is always the empirical formula. We can obtain the chemical formula from the empirical formula if we know the molecular weight of the compound.
For example, consider a covalent compound whose empirical formula is determined to be CH 2 O. The empirical formula mass for this compound is approximately 30 amu (the sum of 12 amu for one C atom, 2 amu for two H atoms, and 16 amu for one O atom).
For example, the molecular formula for acetic acid, the component that gives vinegar its sharp taste, is C 2 H 4 O 2. This formula indicates that a molecule of acetic acid (Figure 3.3.6 3.3. 6) contains two carbon atoms, four hydrogen atoms, and two oxygen atoms. The ratio of atoms is 2:4:2.
