Answer:
The vapor pressure for the first solution at 20°C is 17.48 Torr.
The vapor pressure for the second solution at 20°C is 17.49 Torr.
Explanation:
1) mass of solute that is glucose = 10 g
Moles of glucose ,
Mass of water = m
Volume of water = V = 1L = 1000 mL
Density of water = 1 g/ml
Moles of water =
Vapor pressure of the solution =
Vapor pressure of the pure solvent that is water =
Mole fraction of solute=
The vapor pressure for the first solution at 20°C is 17.48 Torr.
2 ) mass of solute that is sucrose= 10 g
Moles of sucrose ,
Mass of water = m
Volume of water = V = 1L = 1000 mL
Density of water = 1 g/ml
Moles of water =
Vapor pressure of the solution =
Vapor pressure of the pure solvent that is water =
Mole fraction of solute=
The vapor pressure for the second solution at 20°C is 17.49 Torr.
