what is molecular formula? state with example what information can be derived from a molecular formula.

Molecular Formula:-  The molecular formula of a compounnd is actually a chemical formula which represents the true formula of its molecule. Or in other words, it is the multiple of empirical formula showing the actual no. of atoms present in the compound.

For ex:-the empirical formula of glucose is CH2O but the molecular formula is six times multiple of the empirical formula as;


  • Molecular formula explains about no. of atoms in a molecule. Since, a molecule represents a compound , so the  molecular formula explains the contents of compound.
  • It gives an outline of structural formula.
  • It explains the physical and chemical behaviour of compound such as; C2H5 -NH2 explains that Ethanamine, must possess some amine like properties.
