A solution is prepared by dissolving 40.0 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)198 mm Hg B)20.5 mm Hg C)23.6 mm Hg D)24.0 mm Hg

Question

Quizplus · Accepted Answer

The vapor pressure of the solution can be calculated using Raoult's Law. The mole fraction of water is needed, which is calculated by dividing the moles of water by the total moles of the solution. The vapor pressure of the solution is then the mole fraction of water times the vapor pressure of pure water. The calculation shows that the vapor pressure is approximately 23.6 mm Hg.
