A mixture of 120 g toluene and 85.0 g 1,1-dichloroethylene (1,1-DCE) are in a 55 gallon drum sealed cylinder at 25oC and 1 atm of total pressure. Note that p0 = 0.038 atm for toluene at 25C, p0 = 0.30 atm for 1,1-DCE at 25C. Assume that toluene and 1,1-DCE form an ideal mixture in the liquid phase. a. What are the partial pressures of each gas inside the cylinder (in atm and psig)? b. What is the concentration of each gas inside the drum (in g/m3)?
