One mole of complex compound C o N H 3 3 C l 3 gives 3 moles of ions on dissolution in water. One mole of the same complex reacts with two moles of A g N O 3 solution to yield two moles of AgCl(s). The structure of the complex is

Step-by-step solution

C o N H 3 5 C l 3 is correctly written as C o N H 3 5 C l C l 2 which on ionization gives 1 + 2 = 3 moles of ions out of which 2 moles of C l - ions are present which react with 2 moles of A g N O 3 to give 2 moles of AgCl(s).
