27. Solving a chemistry problem

4. Calculate the osmotic pressure of a 1 M aqueous solution of sucrose, knowing that at 30 C the vapor pressure of the solution is 31.207 mm Hg. The vapor pressure of water at 30 C is 31.824 mm Hg. The density of pure water at this temperature (0.99564 g/cm3) can be used to determine V1 of a dilute solution. To solve this problem, Raoult´s law must be introduced into the equation V1Posm = -RT* InX1 , = RT ln( 1 - X2).
