The boiling point of 1M aqueous solution of KCl (85% dissociation) having density \(1.04\ \text{g mL}^{-1}\) is \[ \text{(Given: } K_b(\mathrm{H_2O}) = 0.52\ \mathrm{K\ kg\ mol^{-1}}, \quad \text{Molar mass of KCl} = 74.5\ \mathrm{g\ mol^{-1}} \text{)} \]

At \(298K\), the vapour pressure of pure water is \(25\ torr\). The vapour pressure of water, when \(12\ g\) of urea \((\text{molar mass }=60\ g\ mol^{-1})\) and \(36\ g\) of glucose \((\text{molar mass }=180\ g\ mol^{-1})\) is dissolved in \(100\ g\) of water at the same temperature \((in\ torr)\) is

Which of the following solution has the highest freezing point?

\(0.05\) mole of a non-volatile solute is dissolved in \(500\,g\) of water. What is the depression in freezing point of resultant solution?
\((K_f(H_2O)=1.86\,K\,kg\,mol^{-1})\)
