In coordination chemistry there are a veriety of methods applied to find out the structure of complexes. One method involves treating the complex with known reagents and from the nature of reaction, the formula0 of the complex can be predicted. An isomers of the complex Co(en)_(2)(H_(2)O)Cl_(2)Br, on reaction withconcentrated H_(2)SO_(4) (dehydrating agent ) it suffers loss in weight and on reaction with AgNO_(3) solution it gives a white precipitate which is soluble in NH_(3)(aq). If one moles of original complex is treated with excess (Pb(NO_(3))_(2) solution, then the number of moles of white precipitate ( of PbCl_(2)) formed will be :
