Answer the following questions about vapor pressure of aqueous solutions: a. Calculate the vapor pressure of a solution prepared by dissolving 125.0 g of table sugar (sucrose, molar mass = 342.3 g/mol) in 500.0 mL of water. At 25 degree C the density of water is 0.9971 g/mL and vapor pressure is 23.76 torr. b. Repeat the calculation for 125.0 g of calcium chloride. c. How do your answers to parts a. and b. compare? Account for any similarities or differences.
