3. What is the normal freezing point of 3.15 m aqueous solution of LiNO3? (kf of water = 1.86°C/m) 4. A solution prepared by dissolving 32.10 g organic compound in 74.80 g Carbon tetrachloride boils at 69.5 oC. Determine the molar mass of the compound (boiling point of carbon tetrachloride = 66.4 oC, kb - 5.16 oC/m) 5. What is the vapor pressure of solution at 25 oC prepared by mixing 19.5 g glucose (C6H1206) in 70.5 g water? Vapor pressure of water at 25 oC is 25.3 mmHg.
