Question 1

A solution of methanol and water has a vapour pressure of 248 Torr. What would you predict as the mole fractions of each component, assuming ideal behaviour? The vapour pressures of methanol and water are 256 Torr and 55.3 Torr, respectively.


◦

χ

methanol = 0.960,

χ

water = 0.040
◦

χ

methanol = 0.990,

χ

water = 0.010
◦

χ

methanol = 0.940,

χ

water = 0.060
◦

χ

methanol = 0.900,

χ

water = 0.100
◦

χ

methanol = 0.910,

χ

water = 0.090

Question 2

Choose the aqueous solution that has the highest boiling point. These are all solutions of nonvolatile solutes and you should assume ideal van't Hoff factors where applicable.
◦ 0.100 mol kg-1 AlCl3
◦ 0.100 mol kg-1 C6H12O6
◦ 0.100 mol kg-1 MgCl2
◦ 0.100 mol kg-1 NaCl
◦ They all have the same boiling point.
