EX:

69.7 grams of a solute with a molecular mass of 2790 grams are dissolved in enough water to make 1.00 dm^3 of solution degrees C. What is the osmotic pressure of the solution?

Ex:

Calculate the molecular mass of the nonionic solutes.

8.02 grams of solute in 861 grams of water lower the freezing point to -0.430 degrees C.



Ex: 

Compute the boiling point of this solution:

25.5 g C7H11NO7S (4-nitro-2-toluenesulfonoic acid dihydrate) in 1.00 x 10^2 g H2O (nonionizing solute)

Freezing point of H2O is lowered 1.86 degrees C per mole of solute.

Boiling point of H2O is raised 0.512 degrees C per mole of solute.

Compute the freezing point of this solution:

2535 g C7H11NO7S (4-nitro-2-toluenesulfonoic acid dihydrate) in 1.00 x 10^2 g H2O (nonionizing solute)
