It is the formula in which exact no. of atoms of different elements are present in a compound
e.g. C6H12O6 is the molecular formula of glucose
the three information given by the molecular formula of H2O are as follows :
(i) here 2atoms of hydrogen and 1 atom of oxygen is present.
(ii) by this formula we can find the molecular mass of a molecule that is 18u.
(iii) we can easily find the valeancy of the element like in H2O. the valency of hydrogen is 1 and valeancy of oxygen is 2
