EXERCISE 12.8-VAPOUR PRESSURE OF SOLUTIONS, NON-VOLATILE SOLUTEAssume you dissolve 10.0 g of sucrose (C12H22011) in 225 g of water and warm the solutionto 60 °C, at which temperature the equilibrium vapour pressure above pure water (p°) is19.9 kPa. What is the vapour pressure of water over the solution?We can derive from Raoult's law a direct relationship between the magnitude of thelowering of the vapour pressure, Apsolvent and the mole fraction of the solute. We beginwith the meaning of ApsolventAPsolvent = P solvent%3DnioSubstituting for psolvent in Raoult's law, we havemApsolvent= p°solvent - (Xsolvent X p°solvent) = (1 – xsolvent)P°solventInanysolution, the sum of the mole fractions of solvent and solutes is 1. If there isonly one solute:3D1SO1- Xsolvent = Xsolute|Xsolvent + Xsoluteand the equation for Apsolvent can be rewritten asAPsolvent = XsoluteX p°solvent%3DThis equation tells us that the amount by which the vapour pressure of the solventabove the solution is less than that of the pure solvent is proportional to the mole fractionof solute.
