Glycerin (C_3 H_8 O_3) is a nonvolatile nonelectrolyte with a density of 1.26 g/mL at 25 degree C. Using Raoult's Law calculate the vapor pressure at 25 degree C of a solution made by adding 50.0 mL of glycerin to 500.0 mL of water. The vapor pressure of pure water at 25 degree C is 23.8 torr and its density is 1.00 g/mL. Order the following aqueous solutions in order of increasing osmotic pressure: 0.1 M KCl, 0.1 M sucrose (C_12 H_22O_11) 0.05 M K_2 SO_4 and 0.3 M CaCl_2 Arrange the following five solutions in the order of increasing boiling point elevation, delta T_b, and state your reasons 0.25 m sucrose 0.15 m KNO_3 0.15 m acetic acid, CH_3COOH 0.15 m H_2SO_4
