Chemistry - Liquid Solution Question with Solution | TestHub

$$\begin{array}{ll}& \Delta {\mathrm{T}}_{\mathrm{f}}=\mathrm{iK}{\mathrm{K}}_{\mathrm{f}}\mathrm{m}\\ \therefore & 0.43=\mathrm{i}\times 1.86\times 0.1\\ \therefore & \mathrm{i}=\frac{0.43}{1.86\times 0.1}=2.3\end{array}$$ [Note: In the question, the freezing point of aqueous solution is changed from $-0.43\mathrm{K}$ to $-0.43^{\circ }\mathrm{C}$ to apply appropriate textual concepts.]
