This is an exercise in Raoult's Law. In Example 8, we calculated that the vapor pressure of a 30.2% aqueous solution of ethylene glycol at 100°C is 85.1 mmHg less than the vapor pressure of pure water. The mole fraction of water in the solution is . On the other hand, the addition of ethylene glycol to water, increases the boiling point significantly. A flask of water is connected to a vacuum pump. We know we're gonna have 340 grams of H 20 And at 40 degrees Celsius, the vapor pressure of water is 55.3 and we want it to be reduced by 2.88 So we're looking for a vapor pressure of 52.42 Um, first, we need to figure out what the mole fraction of this will be.
