Glossary of Variables

How It Works: A Step-by-Step Example

For a solution with a pure component vapor pressure of 42.2 kPa and a mole fraction of 0.5, the vapor pressure is calculated as follows:

P = 42.2 × 0.5 = 21.1 kPa

Frequently Asked Questions (FAQ)

What is Raoult's Law?

Raoult's Law states that the partial vapor pressure of each component in a solution is equal to the vapor pressure of the pure component multiplied by its mole fraction in the solution.

How do I calculate mole fraction?

The mole fraction is calculated by dividing the moles of the component by the total moles of all components in the solution.

Can Raoult's Law be used for all solutions?

Raoult's Law is ideally applicable to ideal solutions. Deviations can occur in non-ideal solutions.
