Answer:
The molality of the solution is 0.555 mol/kg.
Mole fraction of water is 0.99.
Mole fraction of sucrose 0.0098.
Explanation:
Mass of sugar syrup solution = 214.2 g
Mass of sucrose = 34.2 g
Mass of solution = mass of solute + mass of solvent
214.2 g = 34.2 g + mass of solvent
Mass of solvent = 180 g = Mass of water
Moles of sucrose =
Moles of water =
Mole fraction of sucrose =
Mole fraction of water=
The molality of the solution is 0.555 mol/kg.
