At 363 K, the vapour pressure of A is 21 kPa and that of B is 18 kPa. ...
Given Information:
- Vapour pressure of A at 363 K = 21 kPa
- Vapour pressure of B at 363 K = 18 kPa
- Number of moles of A = 1
- Number of moles of B = 2
To find: Vapour pressure of the mixture
Solution:
1. Calculation of mole fraction of A and B in the mixture:
- Total moles of the mixture = 1 + 2 = 3
- Mole fraction of A = 1/3
- Mole fraction of B = 2/3
2. Calculation of partial pressures of A and B in the mixture:
- Partial pressure of A in the mixture = mole fraction of A × Vapour pressure of A
= (1/3) × 21 kPa = 7 kPa
- Partial pressure of B in the mixture = mole fraction of B × Vapour pressure of B
= (2/3) × 18 kPa = 12 kPa
3. Calculation of total vapour pressure of the mixture:
- Total vapour pressure of the mixture = partial pressure of A + partial pressure of B
= 7 kPa + 12 kPa
= 19 kPa
Therefore, the vapour pressure of the mixture is 19 kPa.
- Vapour pressure of A at 363 K = 21 kPa
- Vapour pressure of B at 363 K = 18 kPa
- Number of moles of A = 1
- Number of moles of B = 2
To find: Vapour pressure of the mixture
Solution:
1. Calculation of mole fraction of A and B in the mixture:
- Total moles of the mixture = 1 + 2 = 3
- Mole fraction of A = 1/3
- Mole fraction of B = 2/3
2. Calculation of partial pressures of A and B in the mixture:
- Partial pressure of A in the mixture = mole fraction of A × Vapour pressure of A
= (1/3) × 21 kPa = 7 kPa
- Partial pressure of B in the mixture = mole fraction of B × Vapour pressure of B
= (2/3) × 18 kPa = 12 kPa
3. Calculation of total vapour pressure of the mixture:
- Total vapour pressure of the mixture = partial pressure of A + partial pressure of B
= 7 kPa + 12 kPa
= 19 kPa
Therefore, the vapour pressure of the mixture is 19 kPa.

At 363 K, the vapour pressure of A is 21 kPa and that of B is 18 kPa. ...
Given: 
= 21 kPa ⇒
= 18 kPa
→ An Ideal solution is prepared by mixing 1 mol A and 2 mol B.
= 21 kPa ⇒ = 18 kPa→ An Ideal solution is prepared by mixing 1 mol A and 2 mol B.
