Calculate the vapour pressure of a solution prepared by mixing 25.5 g of chloroform (CHClâ) and 40 g of dichloromethane (CHâClâ) at 25°C.
Given:
Vapour pressure of pure CHClâ = 200 mmHg
Vapour pressure of pure CHâClâ = 415 mmHg
Molar mass of CHClâ = 119.5 g mol⻹
Molar mass of CHâClâ = 85 g mol⻹
| 1. | 90.40 mm Hg | 2. | 119.5 mm Hg |
| 3. | 348 mm Hg | 4. | 173.9 mm Hg |
