The empirical formula of a compound is the simplest whole number ratio of atoms of each element in the compound. ... For example, the molecular formula of glucose is C 6H 12O 6 but the empirical formula is CH 2O. This is because we can divide each number in C 6H 12O 6 by 6 to make a simpler whole number ratio.

The empirical formula of a compound is the simplest whole number ratio of each type of atom in a compound. It can be the same as the compound's molecular formula - but not always. An empirical formula can be calculated from information about the mass of each element in a compound or from the percentage composition.

Converting the empirical formula to a molecular formula Add up the atomic masses of the atoms in the empirical formula. For example, the empirical formula of a hydrocarbon is CH 2 and its M r is 42. The molecular formula of the hydrocarbon is therefore C 3H 6.

To work out the empirical formula, you need the mass of the magnesium (from step 2) and the mass of the oxygen atoms as well. To find the mass of the oxygen atoms, subtract the mass of magnesium used from the mass of the magnesium oxide (from step 6).

Empirical formula weight = (1 x 12.01g/mol) + (2 x 1.01g/mol) + (1 x 16.00g/mol) = 30.02g/mol. Divide the molar mass for the molecular formula by the empirical formula mass. The result determines how many times to multiply the subscripts in the empirical formula to get the molecular formula.
