Q) A drum that has been used to collect hazardous waste contains an organic phase in which themole fractions of benzene toluene and o-xylene are 0.32 0.27 and 0.21 respectively. At the ambienttemperature of 25°C the vapor pressures of these three chemicals are 0.126 0.038 and 0.012 atm.(a) If the organic phase behaves ideally with respect to Raoult’s law estimate the partial pressures ofthe three major constituents in the head space in the drum.(b) Some rain water that has leaked into the drum and is present as a separate phase. If Henry’s lawapplies to this phase what are the mole fractions of the three constituents in the aqueous solution
