ppartial = xA*PA°
This formula uses 3 Variables
Variables Used
Partial Pressure - (Measured in Pascal) - Partial Pressure is the notional pressure of that constituent gas if it alone occupied the entire volume of the original mixture at the same temperature.
Mole Fraction of Component A in Liquid Phase - The Mole Fraction of Component A in Liquid Phase refers to the mole fraction of component A which is in the liquid phase.
Vapor Pressure of Pure Component A - (Measured in Pascal) - Vapor Pressure of Pure Component A is the pressure exerted by a liquid or solid molecules of only A in a closed system in which they are in equilibrium with the vapour phase.
STEP 1: Convert Input(s) to Base Unit

What is partial pressure in Raoult's law?

Partial pressure is the pressure that would be exerted by one of the gases in a mixture if it occupied the same volume on its own. Partial Pressure (using Raoult's Law) calculates the partial pressure of a given component in a mixture when the component's mole fraction in the liquid phase and its pure vapor pressure is known.

How to Calculate Partial Pressure of Component A in Raoult's Law?

Partial Pressure of Component A in Raoult's Law calculator uses Partial Pressure = Mole Fraction of Component A in Liquid Phase*Vapor Pressure of Pure Component A to calculate the Partial Pressure, The Partial Pressure of Component A in Raoult's Law is the notional pressure of that constituent gas if it alone occupied the entire volume of the original mixture at the same temperature. Partial Pressure is denoted by ppartial symbol.
