We know that Kb for water = 0.52 k/m

\mathrm{k_f=1.86 \; \mathrm{k} / \mathrm{m}}

\begin{aligned} \mathrm{\Delta T_b =k_b \times m} \\ \end{aligned}

\begin{aligned} \text{m}& =\frac{0.1}{0.52} \\ \end{aligned}

\begin{aligned} \Delta \mathrm{T_f }& = \mathrm{k_f} \times \mathrm{m} \\ & =1.86 \times \frac{0.1}{0.52} \end{aligned}

            =0.357

\therefore  The freezing point of the solution

              \\=0-0.357\\\\=-0.357
