An empirical formula is the lowest whole number ratio of the
elements in a compound and provides information about the
composition of a compound. For instance, the compound sodium
sulfate decahydrate has the chemical formula Na2SO4•10H2O. This
formula conveys the information that there are ten water molecules
per two sodium ions per one sulfate ion. You might wonder: “How
were these ratios determined?” To answer the question it is
necessary to recognize that the ratio of atoms (or ions) is...
