a.) 0.100 m NaNO3
b.) 0.100 m glucose
c.) 0.100 m CaCl2

Answer 1

what are you ranking them by?

Answer 2

in order of decreasing boiling point.

Answer 3

so this is a question of colligative properties. do you have a formula for finding the change in boiling point?

Answer 4

ΔTb = Kb x mB

Answer 5

since the concentrations of all 3 are the same, and the Kb is the same, what's the only difference between those 3 solutions?

Answer 6

.

Answer 7

the solutes are different.
