A solution was prepared by dissolving 0.834 g of sulfur, S8, in 100.0 g of acetic acid, HC2H3O2. Calculate the freezing point and boiling point of the solution. (Use the table from the textbook.)

Answer 1

mols S8 = grams/molar mass
Solve for mols.

molality = m = mols/kg solvent
Solve for m

delta T = Kf*m
Find delta T and subtract delta T from normal freezing point to find new freezing point.

delta T = Kb*m
Find delta T and add to normal boiling point to find new boiling point.
