C. 0.05 m C6H12O6
D. 0.15 m C6H12O6
I think it is D... is that correct?

Which of the following would have the lowest boiling point?
A. 0.8 m C6H12O6
B. 0.10 m C6H12O6
C. 0.05 m C6H12O6
D. 0.5 m C6H12O6

I think it is C... is that correct?

Answer 1

right on both.
Vapor pressure depression with a nonvolitle solute depends on concentration, as does boiling point elevation.
