Calculate the boiling points of freezing points of the following solutions in water.
a) boiling point of a 2.25m solution of propylene glycol (a non-electrolyte)
b)freezing point of a 1.0m solution of potassium iodide
c)freezing point of a 1.0m solution of nickel(II) nitrate
d)boiling point of a .50m solution of sodium chloride
Too many of the same kind of problem.
delta T = Kb*m for boiling point
delta T = Kf(m for freezing point.
for b, c, and d, add an i to the formulas (i.e., delta T = i*Kf*m or delta T = i*Kb*m) where i stands for the number of particles. For b and d that is 2. For c it is 3.
