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 Vapor Pressure of Pure Liquid A in Raoult's Law?

Vapor Pressure of Pure Liquid A in Raoult's Law calculator uses Vapor Pressure of Pure Component A = Partial Pressure/Mole Fraction of Component A in Liquid Phase to calculate the Vapor Pressure of Pure Component A, The Vapor Pressure of Pure Liquid A in Raoult's Law is that pressure exerted by a liquid or solid molecules of only A in a closed system at which they are in equilibrium with the vapor phase. This pressure also corresponds to the boiling point of component A. Vapor Pressure of Pure Component A is denoted by PA^o symbol.
