CHEMISTRY CALCULATORS
Raoult’s Law Calculator
Calculate vapor pressures of solutions using Raoult’s Law. Perfect for chemistry students and professionals.
What is the Raoult’s Law Calculator & How does it work?
Raoult’s Law describes the relationship between the vapor pressure of a solution and the mole fraction of the solvent. It states that the partial vapor pressure of each component in a solution is equal to the mole fraction of that component times its vapor pressure in the pure state.
This law is particularly useful in understanding how solutes affect the vapor pressure of a solution, which can be crucial in various chemical processes and applications.
P_{solution} = X_{solvent} times P^{circ}_{solvent}
Psolution = Vapor pressure of the solution
Xsolvent = Mole fraction of the solvent
Pcirc}solvent = Vapor pressure of the pure solvent
Xsolvent = Mole fraction of the solvent
Pcirc}solvent = Vapor pressure of the pure solvent
