The symbolic representation of the composition of a molecule is known as a molecular formula.
It indicates the number of atoms of different elements present in one molecule of the compound.
Example:
is the molecular formula of water.
Significance of molecular formula:
With the help of molecular formulas, all the elements present in a compound can be known. For example: for water, it tells us that water is made up of Hydrogen H and Oxygen O
The number of atoms of each type of atom present in a compound can also be known. For example: in water, two atoms of hydrogen and one atom of oxygen are present.
The relative molecular mass of a compound can be calculated by the addition of the relative atomic mass of atoms if the molecular formula is known. For example: The relative atomic mass of hydrogen and oxygen is 1amu and 16amu So the relative molecular mass of water is 18amu.
