Mole is the measurement in chemistry. ... One mole is definedas the amount of substance of a system which contains as many entities like, atoms, molecules and ions as there are atoms in 12 grams of carbon - 12". Avogadro number: The number of the particles present in one mole of any substance = 6.022x10 23.

firstly remember the more units6.03
×10 23 The mole concept is one of the topics with which you kick-off your preparation of physical chemistry in class 11. One of the reasons for it being taught earlier is that the concept of mole will be required in almost every other topic of physical chemistry that you study later, irrespective of the complexity of that topic. Apart from its relevance in chemistry, it must be noted that mole concept is one of the easier topics of chemistry, so, make sure you do study it well and go through each and every point in this topic. To help you in your preparations, here, I have discussed the relevant points and formulae that you must know, related to the concept of mole.
Definition of mole –
To start with, you must be very clear about what exactly does a mole represent.
The mole is the unit of measurement in the International System of Units (SI) for amount of substance. 1 Mole is just a number whose value is equal to the Avagadro’s number i.e. 6.022 * 10^23. So, when someone claims of a matter to be of 1 mole in quantity, that implies that the matter under consideration contains exactly 6.022 * 10^23 number of particles (atoms, molecules, ions, electrons or any other elementary entities). This is very similar to the unit ‘dozen’, which is a common analogy used to explain the concept of mole, a dozen is always equal to 12 irrespective of the object referred to.
Why was the concept of mole needed?
When dealing with particles of the size of atoms and molecules, it becomes very difficult to do the calculations as they are present in very large numbers. Even in a small sample of an element or chemical compound, generally the number of elementary particles are in the higher order of 10. So to make these calculations simpler, mole was defined. While solving problems, the numbers are expressed in terms of Avogadro number, making the solution to the problems in physical chemistry simpler.
