AI Generated Solution

To calculate the vapor pressure of the sucrose solution, we will use Raoult's Law, which states that the vapor pressure of a solution (P_s) is equal to the vapor pressure of the pure solvent (P°_A) multiplied by the mole fraction of the solvent in the solution. ### Step-by-Step Solution: 1. **Identify the given values:** - Vapor pressure of pure water (P°_A) = 17.5 mmHg - Mass of sucrose (solute) = 68.4 g - Mass of water (solvent) = 1000 g ...
