Chemical reactions involve interation of atoms and molecules. A large number of atoms // molecules ( approximately 6.023xx10^(23)) are present in a few grams of any chemical compound varying with their atomic // molecular masses. To handle such large numbers conveniently, the mole concept was introduced. This concept has implications in diverse areas such as analytical chemistry, biochemistry, electrochemistry, and radiochemistry. The following example illustrates a typical case, involving chemical // electrochemical reaction, which requires a clear understanding of the mole concept. A 4.0M aqueous solution of NaCl is prepared and 500mL of this solution is electrolyzed. This leads to the evolution of chlorine gas at one of the electrodes ( atomic mass of Na is 23 and Hg is 200)(1F=96500C) . The total number of moles of chlorine gas evolved is

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 adn radiochemistry. The following examples 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 electrolysed. This lead to the evolution of chlorine gas at one of electrodes (atomis mass : Na = 23 , Hg = 200 , 1F = 96500 C) The total number of moles of chlorine gas evolved is :
