Examples of empirical formula The molecular formula of ethane is C 2H 6. It shows the actual number of atoms of each element in a molecule of ethane. This formula does not show the simplest whole number ratio because each number can be divided by two. This gives the empirical formula of ethane: CH 3.

Calculate the empirical formula of the compound from the grams of carbon, hydrogen, and oxygen. Calculate the formula mass for the empirical formula and divide the given molecular mass by the empirical formula mass to get n. Multiply each of the subscripts in the empirical formula by n to get the molecular formula.

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.
