15. A solution of complex salt, CrCl3.6H2O having coordination no. 6 shows an osmotic pressure 73.89 atm at 300 K when 1 M solution of complex is used. One litre of this solution on treatment with excess of AgNO3 solution ( Degree of dissociation = 1) leads to the formation of AgCl : (a) 1 (b) 2 (c) 3 (d) 1.5
