What do you mean by m millimeter?
Also there is not boiling point When sugar is melted, it becomes caramelized.
Note that m stands for molality.
delta T = i*Kb*m
i is the van't hoff factor and is 1 for sugar, glucose and urea. i for NaCl is 2, for BaCl2 it is 3 and for AlCl3 it is 4.
Plug in m, Kb (look up Kb in your text or Google it) and the appropriate i value, then add delta T to the normal boiling point of water (100 C).
Post your work if you get stuck.
