1. Calculate the freezing point and the boiling point of a solution prepared by dissolving 5.0 g of KClin 550 g of water. kf and kb for water are1.86 ºC/m and 0.51 ºC/m, respectively..
2. Calculate the osmotic pressure of a solution containing 24.6 g of glycerin(C3H8O3) in 250.0 mL of solutionat 298 K.
3. A 24.6 g of an unknown(non-electrolyte) molecular compound was dissolved in water to froma 250.0 mL of solution. The resulting solution was found to have anosmotic pressure of 26.1 atm at 25 ºC. Calculate the molar mass of the unknown compound.
