Which of the following statements about boiling points are true?
A. The boiling point of 0.1 m NaF(aq) is lower than the boiling point of 0.1 m methanol(aq).
B. The boiling point of a 0.5 m aqueous solution of LiOH is the same as the boiling point of a 0.5 m aqueous solution of LiCl.
C. The boiling point of a solution made by dissolving 10 g of C2H6O2 in 0.30 kg of water is higher than the boiling point of a solution of 10 g of NaCl in 0.30 kg of water.
D. The boiling point of 2 m KF in water is 102.4ºC.
E. The boiling point of 1 m aqueous KNO3 is higher than the boiling point of 1 m aqueous Ba(NO3)2.
All of these can be answered with delta T = i*Kf*m or i*Kb*m
I can help you if you explain what you don't understand.
