An ideal solution is made by mixing 2 moles of benzene
\((P^o = 266 ~mm) \) and 3 moles of another liquid \((P^o= 236 ~mm) \).
The total vapor pressure of the solution at the same temperature would be:
\((P^o = 266 ~mm) \) and 3 moles of another liquid \((P^o= 236 ~mm) \).
The total vapor pressure of the solution at the same temperature would be:
| 1. | 502 mm | 2. | 248 mm |
| 3. | 600 mm | 4. | 298 mm |

For a dilute solution, Raoult’s law states that:
| 1. | The lowering of vapour pressure is equal to the mole fraction of the solute. |
| 2. | The relative lowering of vapour pressure is equal to the mole fraction of the solute. |
| 3. | The relative lowering of vapour pressure is proportional to the amount of solute in solution. |
| 4. | The vapour pressure of the solution is equal to the mole fraction of the solvent. |
