An aqueous solution of glucose boils at $$100.01^{\circ} \mathrm{C}$$. The number of glucose molecules in a solution containing $$100 \mathrm{~g}$$ of water is _________ [$$\mathrm{K}_{\mathrm{b}}$$ for water is $$0.5 \mathrm{~K} \mathrm{~kg} \mathrm{~mol}^{-1}$$]
The system that forms minimum boiling azeotrope is :
A solution of $$\mathrm{KCl}(\mathrm{M}=74.5 \mathrm{~g} \mathrm{~mol}^{-1})$$ containing $$1.9 \mathrm{~g}$$ per $$100 \mathrm{~mL}$$ of $$\mathrm{KCl}$$ is isotonic with a solution of urea $$(\mathrm{M}=60.0 \mathrm{~g} \mathrm{~mol}^{-1}$$) containing $$3 \mathrm{~g}$$ per $$100 \mathrm{~mL}$$ of urea. The degree of dissociation of $$\mathrm{KCl}$$ is: [Assume both the solutions are kept at same temperature]
Which among the following compounds has the highest freezing point of its 1 molal aqueous solution?
