TALS (CHE 212 Assignment Gradebook Dawnloadable Textbook D A micture of 7.00 gram-moles of benzene and 3.00 gram-moles of toluene are placed in s closed cyinder equipped with a piston The cylinder is immersed in a bath of boiling water that maintains the temperature at 100.0°c The force exerted on the piston can be varied to adjust the eylinder pressure to any desired values pressure is intially 1300 mm Hg and is gradualy lowered to 600 mm Hg. Use the Pry diagram below to convince only liquid benzene and toluene and to answer the following cuestions. 115 110 105 1400 1300 1200 1100 1000 80 0 0.2 0.4 06 0.81.0 0 0.2 0.4 0.6 0.8 1.0 Mole fraction benzene Mole fraction benzene version 4.24.5.

Using Pxy diagram starting from the point (0.7, 1300mm Hg) a vertical line is drawn from that point to the curve. Along the vertical downward line the pressure is reduced to make the mixture saturate during this process the composition of the mixture does not change only pressure is changed and temperature is also kept constant.
The point at which the vertical line first meet the liquid curve will show the bubble point pressure at constant temperature and composition.
Bubble point of the mixture is roughly 1100 mm Hg
Composition of benzene is 0.7 moles of benzene per moles of the mixture
Molar ratio composition 7/3 moles of benzene per moles of toluene
