Q. $2.67 \,g $ of $ CoCl _3 \cdot 6 NH _3$ (molar mass $\left.=267.4\, g\, mol ^{-1}\right)$ in aqueous solution gave $4.305 g$ of white precipitate of $AgCl \left(\right.$ molar mass $=143.5\, g\, mol ^{-1}$ ). On reaction with excess of $AgNO _3$ solution. Thus, $Cl$ atoms in outer sphere of the complex is......
