Chemical reactions involve interaction of atoms and molecules. A large number of atoms and molecules (approximately 6.022 xx 10^(23) ) are present in a few grams of any chemical compound varying with their atomic/molecular masses. To handle such a large number conveniently, the mole concept was introduced. This concept has implications in diverse areas such as analytical chemistry, biochemistry, electrochemistry and radiochemistry. The following example illustrate a typical case involving chemical/electrochemical reaction which requires a clear understanding of mole concept. A 4.0 molar aqueous solution of NaCl is prepared and 500 mL of the solution is electrolyzed. This lead to the evolution of chlorine gas at one of the electrodes (atomic mass : Na = 23 , Hg = 200 , 1F = 96500 C) The total number of moles of chlorine gas evolved is :
