How to calculate vapor pressure?
Vapor Pressure: Vapor pressure is the partial pressure exerted by the vapor of a substance in the gaseous phase of a closed heterogeneous system at equilibrium with condensed phases (i.e. solid or liquid) of the substance present in the system.What is vapour pressure PDF?
Here comes the Vapour pressure formula using Raoult's law, which explains how the vapour pressure of a liquid gets changed by the addition of a solute. P solution = (X solvent )( Po solvent ) X solvent = the mole fraction of the solvent in the solution. P solution = the vapour pressure of the solution.What is vapour pressure and formula?
