$\displaystyle \mathrm{CrCl}_3 . \mathrm{xNH}_3$ can exist as a complex. $\displaystyle 0.1$ molal aqueous solution of this complex shows a depression in freezing point of $\displaystyle 0.558^{\circ} \mathrm{C}$. Assuming $\displaystyle 100 \%$ ionisation of this complex and coordination number of Cr is $\displaystyle 6$ , the complex will be (Given $\displaystyle \mathrm{K}_{\mathrm{f}}=1.86 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$ )
