Molal Boiling Point Elevation Calculator

Calculate the boiling point elevation using: $$ \Delta T_b = i\,K_b\,m $$

* 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
