Molal Boiling Point Elevation Calculator

Calculate the boiling point elevation using: $Δ T_{b} = i K_{b} m$

* Enter the van ‘t Hoff factor $i$ , ebullioscopic constant $K_{b}$ (°C·kg/mol), and the molality $m$ (mol/kg).

Step 1: Enter Parameters

van ‘t Hoff Factor,

i

e.g., 1 (for non-electrolytes) or higher for electrolytes

Ebullioscopic Constant,

K_{b}

(°C·kg/mol):

e.g., 0.51 °C·kg/mol for water

Molality,

m

(mol/kg):

e.g., 1 mol/kg
