Vapor Pressure Benzene - Big Chemical Encyclopedia

Given, vapour pressure of benzene, po=640 mm Hg. Vapour pressure of solution, p=600 mm Hg. Weight of solute, w=2−175g.A liquid at its boiling point has a vapour pressure equal to atmospheric pressure. Therefore the vapour pressure of benzene at 80°C is 760mmHg.Contents 4 Vapor pressure of liquid 5 Distillation data Benzene should NOT be used at all unless no safer alternatives are available.A non-volatile, non-electrolyte solid weighing 0.5 g when added to 39.0 g of benzene (molar mass 78 g mol -1). Vapour pressure of the solution, then, is 0.845 bar.Colligative property about vapor pressure lowering. That's we must use to solve this problem. A mixture of benzene and toluene has a total vapor pressure at 25°C of 45.06 mmHg.
