Question

pls explain the mole concept in detail. i will mark it as brainliest sure

Answer 1

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.

Answer 2

Mole is defined as the amount of a substance, which contains the same number of chemical units (atoms, molecules, ions or electrons) as there are atoms in exactly 12 grams of pure carbon-12. A mole represents a collection of 6.023 x 1023 ( Avogadro's number) chemical units.
