Raoult's Law

Calculate vapour pressure of solutions

⚗️Raoult's Law Calculator

0 to 1

Raoult's Law states that the partial vapour pressure of a volatile component in an ideal solution is proportional to its mole fraction and pure component vapour pressure. P_solution = x_solvent × P°_solvent.

Fun Fact

Raoult's Law only holds perfectly for ideal solutions where intermolecular forces between different molecules are identical to those between like molecules. Real solutions deviate positively or negatively.
