That large a number is difficult to use in calculations so we must use anothermathematical shorthand, scientific notation, to help us.Lets rewrite that same number as: 6.02 E 23Another name for this huge amount: Avogadro' Number.As it turns out this number, named after Amadeo Avogadro, is used as a reference pointfor most calculations and equations found in chemistry.The next section on the main menu deals with the 4 general rules associated with theMOLE concept
Now let me expand on each of these and include lots of examples Sol.Since 56 amu = 1 atom therefore 224 amu = 224 = 4 atomAns..You are welcome totake notes!Rule: The chemical formula represents a mole of that substance.Remember that any number placed to the left of a chemical symbol or formula is calledthe COEFFICIENTDisqus - Questions On Mole Concept Class 11 Pdf DownloadGerigOrganic Chemistry: Made Simpleby SThe chemical formula represents a mole of that substance.II(1956)by Scribd Government DocsBest Books About Chemical CompoundsIntroductory Organic Chemistryby J.T 45e1f1341d
