What are the units of molal elevation constant?
What are the units of molal elevation constant?
Boiling point elevation, ΔTb is given by,
ΔTb = Kb × m where m is molality in mol kg-1 and Kb is molal elevation constant or abullioscopic constant.
∴ Kb = \(\frac{ΔTb}{m}\)
∴ K has units K kg mol-1 (or °C kg mol-1) Therefore, molal elevation constant is the elevation in boiling point produced by 1 molal solution of a nonvolatile solute.
