1. The problem statement, all variables and given/known data A vessel contains a mixture of benzene and o-xylene. At 473K the pressure in the vessel is 1000 kPa (abs). Using the data provided below, and any others necessary, what are the mass fractions of benzene in the liquid and vapour? Assume the liquid phase is an idea liquid mixture and the gas phase behaves like and ideal gas mixture. 2. Relevant equations Raoult's equation P=xP*(T) Antoine's equation P*=exp[A-B/(T+C)] 3. The attempt at a solution I used Antoine's equation to find P*(473). And I know P+P=1000 kPa but I don't know where to go from here. ANy help would be appreciated.
