Consider a solution made by dissolving 331 g of sucrose in 116 ml of water at 45˚C. The vapor pressure of water at 45˚C is 0.095 atm and the density of water at 45˚C is 0.992 g/ml. What is the vapor pressure of the sucrose/water solution, in atm? (Note: The molar mass of sucrose is 180.2 g/mol.)

Expert Solution
Step 1

Given data are,

 given mass of sucrose = 331 g

given volume of water = 116 mL  

density of water = 0.992 g/mL

molar mass of sucrose = 180.2 g/mol

Vapor pressure of pure solvent = 0.095 atm

We need to find vapor pressure of sucrose-water solution.
