Stoichiometry
Saturated solution of benzene in water is in equilibrium with a mixture of air and vapours of benzene and water at room temperature and pressure. Mole fraction of benzene in liquid is xB and the vapour pressures of benzene and water at these conditions are PvB and Pvw respectively. The partial pressure of benzene in air-vapour mixture is

Stoichiometry
Raoult's law states that 'the equilibrium vapor pressure that is exerted by a component in a solution is proportional to the mole fraction of that component'. This generalisation is based on the assumption that the

Attractive forces between like and unlike molecules are approximately equal

All of these

Sizes of the component molecules are approximately equal

Component molecules are non-polar and no chemical combination or molecular association between unlike molecules takes place in the formation of the solution
