Raoults Law Calculator
Result
Raoults Law Calculator Calculate the vapor pressure of a solution using Raoult's Law, and the boiling point elevation. — free online calculator.
Formula
- Raoults Law Calculator calculates its result from Chi Solvent, P Solvent. It uses the formula P_solution = χ_solvent × P°_solvent. Change any input to recalculate the result instantly.
- The main inputs are Vapor Pressure of Pure Solvent (P°), Moles of Solvent, Moles of Solute. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Raoults Law
- Vapor Pressure of Pure Solvent (P°): 23.8 mmHg
- Moles of Solvent: 5
- Moles of Solute: 1
Using Chi Solvent = 2, P Solvent = 3, the calculated result is 6.
