The vapor is in equilibrium with a solution ofM and N at 85°C and the solution can be assumed to be essentially ideally dilute. Considering the figure below drawn as partial and total vapor pressures versus XM,1 for M-N solutions at 85°C; 500 500 450 450 400 400 350 350 300 300 250 250 200 200 150 150 100 100 50 50 0,2 0,4 0,6 0,8 XM,I Fig. Q.I Partial and total vapor pressures for M-N solutions at 85°C a) Draw the lines for partial and total vapor pressures above solutions of M and N at 85°C those would occur for an ideal solution. b) Find the vapor pressures of pure M and pure N at 85°C on the same figure. c) Calculate the vapor phase composition in equilibrium with a solution having xM,I=0.4. d) Find the mass of M that will dissolve in 100.0 g of N at 85°C when pressure of M is 300 torr. Neglect the pressure variations in Henry's law constant (K¡).
