How to Find the Molecular Formula. The molecular formula of a compound can be found with the use of empirical formula. The empirical formula is the chemical formula which gives the ratio between the atoms present in the compound.

Compounds are basically the combination of two or more elements that too in a specific ratio or in relative proportions. A chemical formula is an expression that represents the element in that compound along with its relative proportion in the compound.

So, the chemical formula in chemistry is like a shorthand representation of the elements in a compound using the specific symbols assigned to each element that is mentioned in the periodic table. Is this page helpful?

The empirical formula is the chemical formula which gives the ratio between the atoms present in the compound. It does not give the exact number of each atom present. Before finding the molecular formula, one should find out the empirical formula from the mass percentages of each atom present in the compound.
