I need help with this question

Which would have a higher boiling point?

a.1.0 M KNO3
b.1.5 M KNO3
c.0.75M KNO3
d.2.0M KNO3

1. You can calculate each if your wish or take a short cut.
To calculate,
delta T = i*Kb*m
i is the van't Hoff factor and is 2 for all cases in this question. You know Kb is 1.52.

The shortcut is just i*M since Kb is the same for all of them. The higher i*m the higher delta T. I'll be happy to check your answer.

3. C'mon,
delta T = i*Kb*M
i - 2
]Kb = 1.52
M = 1 M

Then delta T = 2*1.52*1 = ?
dT = 3.04 for a.
The others are done the same way.

Go back and look at my response to your question on the 0.08M monoprotic acid. If you will explain what you don't understand perhaps I can help you through it.
