Molecular Formula:

A chemical formula that shows exact number of atoms of all the elements present in a molecule is called ‘Molecular Formula’ of that compound. It also explains actual ratio between the atoms of elements.

For example:                     Glucose                                C6H12O6

Common Salt     NaCI

Sulfuric acid       H2SO4

Empirical Formula:

A chemical formula which shows the simplest ratio between the atoms of elements present in a molecule is called “Empirical Formula’. Example:   Glucose    CH2O

Benzene              CH

Butane                 C2H5
