According to Raoult's law, PB = PdegB XB
PdegB = 75 torr
XB = (78/78)/(78/78+46/92) = 1/1.5
PB = 75 x 1/1.5 = 50 torr

°C, the vapor pressures of pure benzene and pure toluene are 95.1 mmHg and 28.4 mmHg, respectively.
To determine the vapor pressure of a mixture of benzene and toluene, we can use Raoult's law, which states that the vapor pressure of a component in an ideal solution is equal to the product of the vapor pressure of the pure component and its mole fraction in the solution.
Let's assume that we have a mixture of benzene and toluene with mole fractions xB and xT, respectively.
According to Raoult's law, the vapor pressure of benzene in the mixture (PB) is given by:
PB = xB * P°B
where P°B is the vapor pressure of benzene.
Similarly, the vapor pressure of toluene in the mixture (PT) is given by:
PT = xT * P°T
where P°T is the vapor pressure of toluene.
Since the solution is nearly ideal, we can assume that the total vapor pressure (P) of the mixture is the sum of the vapor pressures of the individual components:
P = PB + PT
Substituting the values given:
P = xB * 95.1 mmHg + xT * 28.4 mmHg
Therefore, the vapor pressure of the mixture of benzene and toluene at 20°C is given by the above equation, where xB and xT are the mole fractions of benzene and toluene, respectively.
