Question

Calculate the molal elevation constant of solvent if boiling point of $0.12\text{ m}$ solution is $319.8\text{ K}$ (Boling point of solvent $= 319.5\text{ K}$ )}

• A. $2.0\text{ K kg mol}^{-1}$
• B. $3.0\text{ K kg mol}^{-1}$
• C. $2.5\text{ K kg mol}^{-1}$
• D. $3.5\text{ K kg mol}^{-1}$

Hint:

$K_b$ is also called the ebullioscopic constant and is characteristic of the solvent.
