Question

For a 0.50 molal solution of sucrose in water, calculate the freezing point and the boiling point of the solution. Please list each step.?

Answer 1

dT = Kf*m or dT = Kb*m
You know m, look up Kf and Kb, solve for dT in each case.
For the new freezing point subtract from the normal freezing point.
For the new b.p., add to the normal boiling point. Post your work if you get stuck.
