Answer:

e. 0.75m CuCl

Explanation:

The boiling point of a solvent increases with the addition of moles of solute. The formula is:

ΔT = i×Kb×m

Where ΔT is boiling point elevation, i is Van't Hoff factor, Kb is ebulloscopic constant and m is molality of solution.

That means <em>the higher i×m, the highest boiling point</em>. Thus:

a. 1.0m KNO₃: i×m = 2ₓ1.0m = <em>2</em>

b. 2.0m C₁₂H₂₂O₁₁: i×m = 1ₓ2.0m = <em>2</em>

c. 0.75m NaCl: i×m = 2ₓ0.75m = <em>1.5</em>

e. 0.75m CuCl: i×m = 3ₓ0.75m = <em>2.25</em>

<em>e. 0.75m CuCl </em>has the highest boiling point
