Calculate the boiling temperature of a 0.50 m solution of sucrose. assume that the concentration is 0.50 m.

There is one missing point in the question.

The formula to find an increase in boiling Temperature is :

ΔT = kb x M

ΔT = is the increase in boiling Temperature
Kb = Boiling point constant of the Solvent
M = Molarity

You did not provide the Kb. If you have it, you just have to insert it to the formula to find the ΔT.

And assuming that the other solution is water, you just have to add it up with 100 Celcius
