Vapor pressure of benzene can be calculated using the Antoine's Equation: InP= 6.9057- 1211 T+220.8 where P is the vapor pressure in torr and T is the temperature in °C. Convert the equation to Sl units.

Question 1. Derive an expression for the vapor density at the boiling point as a function of temperature. Assume that the ideal gas law is valid. The vapor density of water at 25°C is 23.4 g/m³. Calculate the vapor pressure and vapor density at 50°C.

13 An ideal solution of 5.25 moles of benzene and 3.0 moles of toluene is placed in a piston and cylinder assembly. At 298 K, the vapor pressure of pure substances are P°(benzene) = 96.4 torr & P°(toluene) = 28.9 torr. The vapor pressure of the solution is; 69.81 torr O 71.83 torr 53.47 torr O 66.61 torr 67.50 torr
