A solution is prepared by dissolving 50.0 g of sucrose,C₁₂H₂₂O₁₁,in 250.g of water at 25°C.What is the vapor pressure of the solution if the vapor pressure of water at 25°C is 23.76 mm Hg? A)0.247 mm Hg B)19.8 mm Hg C)23.5 mm Hg D)24.0 mm Hg

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 0.987, leading to a vapor pressure of about 23.5 mm Hg.
