The mole concept and avogadro's number a concept used for measure amount of particles like atoms, molecules number of atoms in the 6 c 12 element is equal to 1 mole.
Mole concept photo by: anar musayev in chemistry the mole is a fundamental unit in the système international d'unités, the si system, and it is used to measure the amount of substance. Thus in the above example there was a mole of pennies 1 mole = na objects the mole concept is no more complicated than the more familiar concept of a dozen : 1 dozen = 12 objects from the penny example above one might suspect that the mass of a mole of objects is huge.
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. Mole concept calculation this is the most basic and the most used calculation that a student comes across while solving a mole concept problem most of the times, moles or number of atoms or molecules are given in the question and the mass is needed to be calculated.
Chemical engineers use the concept extensively, but the unit is rather small for industrial use for convenience in avoiding conversions in the imperial (or american customary units ), some engineers adopted the pound-mole (notation lb-mol or lbmol ), which is defined as the number of entities in 12 lb of 12 c.

Mole concept one of the values of the mole is that every mole of any element has the same number of atoms in it we have not yet discussed what that number is in this course (we will deal with that later when we consider the size of atoms), but we do know that it is the same amount for each element.
