Chemical Formula You will also see the term  chemical formula . The  chemical formula  tells you how many  of each type of atom are in a molecule. For example, the  chemical formula  for ethanol is C 2 H 6 O. Notice that this is less information than the  structural formula  (but more compact). You  must be careful not to confuse substances that have the same chemical formula. For  example, ethanol and dimethyl ether have the same chemicial formula ( i.e.  C 2 H 6 O). Their  chemical formulas  are identical, but their structural formulas and their  physiological effects are markedly different.

Unformatted text preview: Empirical Formulas An empirical formula (simplest formula) tells us the simplest whole number ratio of atoms in a molecule. When identifying an unknown pure substance, chemists will often start by performing experiments to determine the empirical formula of the substance. For example, hydrogen peroxide's chemical formula is H 2 O 2 , but its empirical formula is HO. The chemical formula for glucose is C 6 H 12 O 6 , but its empirical formula is CH 2 O, and its structural formula is...
