How to Use This Calculator
  1. Enter the ebullioscopic constant (Kb) for your solvent — water is 0.512 °C·kg/mol.
  2. Set solality in mol/kg and van't Hoff factor (i) for the solute (1 for non-electrolytes, 2 for NaCl, etc.).
  3. Enter the normal boiling point of the pure solvent.
  4. Review Boiling Point Elevation (ΔTb) and New Boiling Point.
