A solution is prepared by dissolving 40.0 g of sucrose,C₁₂H₂₂O₁₁,in 250.g of water at 25 °C.What is the vapour pressure of the solution if the vapour pressure of water at 25 °C is 23.76 mmHg? A)0.198 mmHg B)20.5 mmHg C)23.6 mmHg D)24.0 mmHg

Question

Quizplus · Accepted Answer

The vapor pressure of the solution is calculated using Raoult's Law. The mole fraction of water is used to find the vapor pressure of the solution. The mole fraction of water is approximately 0.992, leading to a vapor pressure of about 23.6 mmHg.
