Question

Chloroform, CHCl₃, boils at 61.7°C. If Kb for chloroform is 3.63°C/molal, what is the boiling point of a solution of 15.0 g of CHCl₃ and 0.616 kg of acenaphthalene (C₁₂H₁₀)?

• A. \(61.9^\circ\text{C}\)
• B. \(62.0^\circ\text{C}\)
• C. \(52.2^\circ\text{C}\)
• D. 62.67°C

Hint:

Boiling point elevation depends only on number of solute particles.

Answer 1

The Correct Option is D
