Determining lowest vapor pressure
WebIn assessing hazards, it is very important to know the vapour pressure of a substance. The vapour pressure is the pressure at which a liquid and its vapour are in equilibrium at a given temperature. The vapour is said to be "pushing" against the atmosphere. In other words, the higher the vapour pressure the faster a liquid evaporates. WebJan 10, 2024 · It usually has a low vapor pressure and a high boiling point. A good example of a non-volatile solution is that of sugar water. ... Calculate the vapor pressure for a mixture of pure toluene (C 7 ...
