a)How much would the freezing point change in a 2.5m solution of phenol in benzene? (freezing point of phenol is 7.40 degrees C, freezing point of benzene is 5.12 degrees C)

b)How much would the boiling point change in a 1.0m solution of magnesium chloride in ethanol? (boiling point of ethanol is 1.19 degrees C)
Answered by DrBob222
a)
delta T = Kf*m

b)
delta T = i*Kb*m
i is the van't Hoff factor which for MgCl2 is 3 (for three particles).
