Calculating the Vapor Pressure of a Benzene and Water Solution?
At 25 degrees celsius, benzene (C6H6) has a vapor pressure of 18.1 kPa. Calculate the vapor pressure of a 20 degrees celsius benzene and water solution with a benzene mole fraction of 0.5.
Can someone please explain to me how to do this problem?

we need the vapor pressure of water at 20 °C for the calculation.
p(total) = (p(benzene))*(mole fraction benzene) + (p(water))*(mole fraction water)
p(total) = (18.1 kPa)*(0.5) + (p(water))*(0.5)
