The volume $\left(\mathrm{i}\mathrm{n} \mathrm{m}\mathrm{L}\right)$ of $0.125 \mathrm{M} {\mathrm{A}\mathrm{g}\mathrm{N}\mathrm{O}}_3$ required to quantitatively precipitate chloride ions in $0.3\mathrm{g}$ of $\left[\mathrm{C}\mathrm{o}{\left(\mathrm{N}{\mathrm{H}}_3\right)}_6\right]\mathrm{C}{\mathrm{l}}_3$ is __________.
${}^{\mathrm{M}}\left[\mathrm{C}\mathrm{o}{\left(\mathrm{N}{\mathrm{H}}_3\right)}_6\right]\mathrm{C}{\mathrm{l}}_3=267.46\mathrm{g}/\mathrm{m}\mathrm{o}\mathrm{l}$
${{}^{\mathrm{M}}\mathrm{A}\mathrm{g}\mathrm{N}\mathrm{O}}_3=169.87\mathrm{g}/\mathrm{m}\mathrm{o}\mathrm{l}$
