Hello aspirant,

The unit of ebullioscopic constant constant is K kg (mol)^-1 or K molality^-1.

ΔTb=Kb × molarity

Kb=molarityΔTb= Kelvin (molarity)−1 or K Kg mol−1

Hope, this answer helps you.

Hello,

Ebullioscopic constant (E _b ) is the constant that expresses the amount by which the boiling point T _b of a solvent is raised by a nondissociating solute, through the relation. ΔT _b = E _b b. where b is the molality of the solute. The unit of ebullioscopic constant is K kg mol ^{- 1} or K molality ^{- 1}
