The vapour pressures of A and B at 25°C are 90 mm Hg and 15 mm Hg,...
°C are 60 mmHg and 90 mmHg, respectively. If a mixture of A and B with mole fraction of A is 0.4 is prepared, what is the total vapor pressure of the mixture at 25°C?
To find the total vapor pressure of the mixture, we can use Raoult's law, which states that the vapor pressure of a mixture is equal to the sum of the partial pressures of the components in the mixture, each multiplied by its mole fraction:
P_total = P_A * x_A + P_B * x_B
where P_A and P_B are the vapor pressures of A and B, respectively, and x_A and x_B are their mole fractions in the mixture.
Substituting the given values, we get:
P_total = 60 mmHg * 0.4 + 90 mmHg * 0.6
P_total = 24 + 54
P_total = 78 mmHg
Therefore, the total vapor pressure of the mixture at 25°C is 78 mmHg.

The vapour pressures of A and B at 25°C are 90 mm Hg and 15 mm Hg,...
xA = 0.6
PT = xAPAo + xBPBo
= 0.6 × 90 + 0.4 × 15
= 54 + 6 = 60
xAPAo = yAPT
0.6 × 90 = yA(60)
yA = 0.9
yB = 0.1 = 1 × 10-1
∴ x = 1
PT = xAPAo + xBPBo
= 0.6 × 90 + 0.4 × 15
= 54 + 6 = 60
xAPAo = yAPT
0.6 × 90 = yA(60)
yA = 0.9
yB = 0.1 = 1 × 10-1
∴ x = 1
