b) List the four colligative properties that were discussed in this chapter. 2) What is the molality of a solution prepared by dissolving 0.265g of glucose, C6H12O6, in 145.0g water, H2O ? 3) The vapor pressure of pure water at 25C is 23.76mmHg. What is the vapor pressure of a solution made from 1.75mol sucrose in 13.5mol of water at 25C ? Sucrose is a nonvolatile solute. 4) What is the freezing point ( in C ) of a solution prepared by dissolving 2.89g of NaCl in 95g of water? The van't Hoff factor for NaCl is i=1.9. 5) Calculate the osmotic pressure of a 0.85M glucose solution in water at 355K
