Mole is the essential mathematical tool in the field of science. Mole Concept is very useful not only in chemistry but also in physics Mathematics and Biology. Mole Concept provides a wide range of calculation in the field of science. Mole is not a definition as it is usually projected but it is a concept to understand the wide range of calculations. 

Eudiometry is actually gas analysis. In gaseous reactions Eudiometry provides very important calculations and very frequently Numericals based on Eudiometry are asking in various Competitive examinations specially in JEE, AIPMT. In NCERT XI Exercise of Chapter 1 Some basic concepts in physical chemistry Question no. 1.34 is based upon Eudiometry but in school level education it is not explained properly whereas it is very important calculation, Similarly one more thing is related with the Eudiometry and that is POAC (Principle of Atomic conservation) which is also a very important part under Mole concept and all these things introduce very important mathematical operations. So this is very interesting topics and for this, if you are attending my free class you can understand my teaching method and you also come to know that how I am making the chemistry subject very easy and smooth and intresting so that you can grasp every thing easily and also you can develop a skill to solve all types of questions in intersting way.
