Introduction to Mole Concept | Chemistry By ALK Sir |Physical Chemistry Class 11 | IIT JEE Main and Advanced


In this video lecture by Alok Kumar Sir ( #ALK_Sir ) Mole, a concept chapter has been Introduced in which a detailed definition of Mole has been given.
Topics covered in this Introduction to Mole Concept (Class 11) Lecture by ALK sir with timestamp:-
00:00 - 05:00 :- Introduction to the concept of mole.Definition and units of relative atomic mass ,atomic mass and gram atomic mass
05:01 - 06:40 :- Mol is defined as the amount of substance which contains as many atoms/molecules /ions which are equal to number of atoms in 12 g of C-12 isotope.Value of Avogadro number is discussed.
06:01 - 10:14 :- Sir has discussed different methods to calculate number of moles of solid,liquid and gaseous substances
10:15 - 15:00 :- STP and NTP conditions are explained .In old definition of STP volume is 22.4 lit and pressure is 1 atm and in new definition of STP 22.7 lit is volume and 1 bar is the pressure.The lowest value of molar volume of gas at STP is 22.7 lit.
15:01 - 23:05 :- Conversion of gas parameters into STP and NTP conditions using ideal gas equation PV=NRT.SI units and values of P ,V ,R and T are discussed.
23:06 - 27:26 :- Problem 1: We have to calculate a) no of moles of glucose b)no of moles of C,H,O atoms, d) mass of C e)Number of oxygen atoms in 90 gm of C6H12O6.ALK sir has solved the question by first calculating number of moles of glucose and then proceeded further applying mole concept.
Chapter - Mole Concept is very important wrt JEE mains & advanced. This is the first lecture of the Mole Concept Chapter of class 11 Physical Chemistry for JEE Mains & Advanced. There are total 12 lectures in one mole concept chapter class 11.
ALK sir is covering all topics, concepts, examples, and problems that are important for JEE Mains and Advanced. This introduction to mole concept class 11 Chemistry lecture consists of the Basic introduction of mole concept . This lecture is for the Science student of class 11 who is preparing for JEE Mains & Advanced or Olympiad. ALK sir also covered JEE ADVANCED PYQ in this lecture.
