Solution
The correct option is A 0.001 The molecular formula of dichlorotetraaquachromimum (III) chloride can be represented as [Cr(H2O)4Cl2]Cl,. Thus, it contains one ionizable Cl−.
Hence, an excess of AgNO3 is added to 100 mL of a 0.01 M solution of dichlorotetraaquachromimum (III) chloride. The number of moles of AgCl precipitated would be 0.001.
