How do you do this?

Calculate the increase in the boiling point, ΔT, for a 0.53 m solution of sucrose (dissolves as a molecule) in water.

delta T = i*Kb*m

You need to know that for sucrose i = 1
You need to look up the Kb for water. I think that's 0.512 oC/m but you should confirm that. You're given m. Plug and chug.
