Cobalt (III) chloride forms a green coloured complex ' X ' with $\mathrm{NH}_3$. Number of moles of AgCl formed when excess of $\mathrm{AgNO}_3$ solution is added to 100 mL of 1 M solution of ' X ' is
  1. 0.3
  2. 0.2
  3. 0.1
  4. 1

Solution


$\begin{aligned} & \text { Volume given }=100 \mathrm{ml} \\ & \qquad \begin{aligned} & =10^{-1} \mathrm{~L}\end{aligned} \\ & \begin{aligned} \text { Concentration } & =1 \mathrm{M}\end{aligned} \\ & \begin{aligned} \text { Concentration } & =\frac{\text { number of mole }}{\text { Volume }} \\ \therefore \quad \text { Number of mole } & =1 \times 10^{-1} \\ & =0.1 \mathrm{~mole}\end{aligned}\end{aligned}$
