Consider a 15.0 mL sample of a ternary mixture composed of 25% (by volume) octane, 35% chloroform and 40% 2-propanol. Use the following information to convert volume composition to molar composition:
• Octane (C8H18): formula mass: 114.23 g/mol; density: 0.702 g/mL; bp: 125.7 C
• Chloroform (CHCl3): formula mass: 119.38 g/mol; density: 1.48 g/mL; bp: 61.7 C
• 2-propanol (C3H8O): formula mass: 60.11 g/mol; density: 0.786 g/mL; bp: 82.4 C
c) Sketch the theoretical distillation curve for 12.0 mL of this ternary mixture. How would you use an experimental distillation curve to determine the unknown %, by volume, composition of any mixture?
