Mole Concept: Advanced Level Problem (ALP) Sheet

Hope you are enjoying solving problems on this platform for Free IIT-JEE  preparation (JEE Main and Advanced). In this post, I am sharing an Advanced Level Problem (ALP) Sheet (as per requests received from students) on Mole Concept for JEE Main and Advanced (Download Link at bottom). It is one of the fundamental topics of JEE Chemistry.

Mole Concept? A Brief Intro.

Atoms and molecules are too small to count. To solve this problem their numbers are expressed in terms of Avogadro’s number (NA = 6.023 1023).  Mole is the number equal to Avogadro’s number just like a dozen is equal to 12, a century means 100, a score means = 20.

Mole can be defined as  a unit which represents 6.023 x 1023 particles of same matter. 

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