Given information:
- Vapour pressure of component A (PA) = 260 mmHg
- Vapour pressure of component B (PB) = 520 mmHg
- Mole fraction of component A (xA) = 0.55
Definition:
The total pressure of an ideal binary mixture is the sum of the partial pressures of its components.
Calculation:
1. Calculate the partial pressure of component A (PA) in the mixture using Dalton's law of partial pressures:
PA = xA * PT
where PT is the total pressure of the mixture.
2. Substitute the given values in the equation:
260 mmHg = 0.55 * PT
3. Solve for PT:
PT = 260 mmHg / 0.55
= 472.727 mmHg
4. Calculate the partial pressure of component B (PB) in the mixture using Dalton's law of partial pressures:
PB = (1 - xA) * PT
5. Substitute the calculated value of PT and given value of xA in the equation:
PB = (1 - 0.55) * 472.727 mmHg
= 0.45 * 472.727 mmHg
= 212.727 mmHg
6. Calculate the total pressure (PT) by adding the partial pressures of both components:
PT = PA + PB
= 260 mmHg + 212.727 mmHg
= 472.727 mmHg
Therefore, the total pressure of the ideal vapour-liquid binary mixture is 472.727 mmHg, which is approximately 377 mmHg (option C).
- Vapour pressure of component A (PA) = 260 mmHg
- Vapour pressure of component B (PB) = 520 mmHg
- Mole fraction of component A (xA) = 0.55

PB = (1 - xA) * PT
5. Substitute the calculated value of PT and given value of xA in the equation:
PB = (1 - 0.55) * 472.727 mmHg
= 0.45 * 472.727 mmHg
= 212.727 mmHg
6. Calculate the total pressure (PT) by adding the partial pressures of both components:
PT = PA + PB
= 260 mmHg + 212.727 mmHg
= 472.727 mmHg
Therefore, the total pressure of the ideal vapour-liquid binary mixture is 472.727 mmHg, which is approximately 377 mmHg (option C).
