The vapour pressure of two liquids 'P' and 'Q' are 80 and 60 torr, respectively. The total vapour pressure of the solution obtained by mixing 3 moles of P and 2 moles of Q would be:
1. 68 torr
2. 140 torr
3. 72 torr
4. 20 torr

A solution has a 1:4 mole ratio of pentane to hexane.
The vapor pressures of the pure hydrocarbons at 20 ºC are
440 mm Hg for pentane and 120 mm Hg for hexane.
The mole fraction of pentane in the vapor phase would be:
| 1. | 0.200 | 2. | 0.478 |
| 3. | 0.949 | 4. | 0.786 |
