Answer:
Mass of glucose = 10 g
No. of moles of glucose = 0.0556
Mass of sucrose = 20 g
No. of moles of sucrose = 0.0585
Mass of water = 100 g
No. of moles of water = 5.556
Total number of moles = 5.556+0.0585+0.0556
=5.67
Mole fraction of water =
5.67
5.556
Vapour pressure of solution = Mole fraction of water ×P
0
=
5.67
5.556
