1) Calculate the vapor pressure for each of the following solutions at 25 °C.a) 26.59 g of C12H22O11 dissolved in 461.9 g of water;2) To what temperature (°C) would a solution containing 27.7 g of C 12H22O11 in400 g of water have to be heated to have a vapor pressure of 89.5 mmHg?3) Determine the freezing point and the boiling point of the solution in 2.4) What is the boiling point of a 9.2% (by mass) solution of benzoic acid(C6H5CO2H) in benzene? Note: kb for benzene is 2.53 °C·molal-1.5) A 3.25 g sample of glycerol dissolved in 26.8 g of water elevated the boiling pointby 0.685 °C.a) What is the molar mass of glycerol?6) Determine the ideal freezing point of a solution prepared by mixing 2.79 g ofCa(NO3)2 in 300. g of water. The observed freezing point is -0.274 °C.
