       Answer:        

A mole of a substance is defined as:

The mass of substance containing the same number of fundamental units as there are atoms in exactly 12.000 g of 12C.

Mole can be defined as  a unit which represents 6.023 x1023 particles of same matter.

A mole is defined as the amount of substance that contains as many atoms, molecules, ions, electrons or any other elementary entities as there are exactly 12 gm of carbon atoms. The number of atoms in 12 gm of is called Avogadro’s number.

     Explanation:      

The mole concept is a convenient method of expressing the amount of a substance. Any measurement can be broken down into two parts – the numerical magnitude and the units that the magnitude is expressed in. For example, when the mass of a ball is measured to be 2 kilograms, the magnitude is ‘2’ and the unit is ‘kilogram’.

When dealing with particles at an atomic (or molecular) level, even one gram of a pure element is known to contain a huge number of atoms. This is where the mole concept is widely used. It primarily focuses on the unit known as a ‘mole’, which is a count of a very large number of particles.
