It’s saying, if there’s 95% benzene in the solution, then the vapor pressure is only going to be 95% of its total value if it were pure. Liquid molecules at the surfaceLiquid molecules at the surface escapeescape into theinto the gasgas phase.phase. Basically, it is a measure of how much the solvent molecules tend to escape from a liquid or solid phase into the atmosphere. A high vapor pressure usually is an indication of a volatile liquid, or one that readily vaporizes. The phase diagram 0 0 for a particular pure liquid can be constructed by using sets of (T, Po) , where P is a function of T only.

The boiling temperature of water for atmospheric pressures can be approximated by the Antoine equation: log10P = 8.07131 - {1730.63/233.426 + Tb} where the Temperature Tb is the boiling point in oC Pressure P is in Torr. The Macroscopic View. The vapor pressure of a pure solvent is greater than the vapor pressure of a solution containing a non volatile liquid. Thus, PA = XAP°o and Ptotal = PA + PB. Volatilization is a function of the concentration of a contaminant in solution and the contaminants partial pressure. This lowers the vapor pressure more than expected. - Chapter 11 Properties of Solutions Solution Composition Molarity (M) = moles solute / Liters solution Mass Percent no units (mass solute / mass solution) x 100 ...
