It is found to be useful to measure quantity by the number of particles, which enables us to calculate the revelant masses and volumes ,
A mole is the number of carbon atom in 12 g exactly of C
the value of one mole is known as Avogadro's number.
mole=atomic weight for an tom = molecular weight of a molecule
thus one mole of H2O =18 g,
The number of moles (for a substance)= weight/molecular weight

One mole is the amount of substance which contains the same amount of particles as there are 12g of carbon-12. The number of atoms in 12 gram of carbon-12 is 6.02x10^23.
