The mole is useful in chemistry because it is defined such that the mass of Avogadro's number of particles (atoms or molecules) of a substance (the molar mass) is equal to the sum of the numerical values of the atomic masses of its constituent elements.
The Mole Concept: A mole is a unit to count the number of atoms, ions or molecules. They believed that, for example, if one molecule of carbon dioxide (CO 2) contained 1 carbon atom and 2 oxygen atoms, then the ratio of carbon atoms to oxygen atoms is 1:2.his unit is called Mole. 6x10 23 is not an equation; it is the number of atoms, ions or molecules in one mole. If you put 6x10 23 in a calculator, you will find out that this number is 600,000,000,000,000,000,000.
