Question 20

Cobalt(III) forms an octahedral complex ion $Y\textbf{Y}$ , which contains both ammonia ( $NH3\text{NH}_3$ ) and chloride ( $Cl−\text{Cl}^-$ ) ligands.

Complex ion $Y\textbf{Y}$ has a molar mass of 197.9 g mol^-1.

Using the relative atomic masses $Co=58.9\text{Co} = 58.9$ , $N=14.0\text{N} = 14.0$ , $H=1.0\text{H} = 1.0$ , and $Cl=35.5\text{Cl} = 35.5$ , determine the formula and charge of complex ion $Y\textbf{Y}$ .
