If excess of AgNO3 solution is added to 100 mL of 2.4 M solution of dichlorobis(ethylenediamine)cobalt(III) chloride, how many moles of AgCl will be precipitated?

Solution
AgNO3+[Co(en)2Cl2]Cl→AgCl↓
moles of [Co(en)2Cl2]Cl present =2.4M×1001000 =0.24mol Since one mole of the given complex produces one mole of AgCl. Hence 0.24 mol of AgCl will be produced from 2.4 M of 100 mL [Co(en)2Cl2]Cl
