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 o
• Chloroform (CHCl3): formula mass: 119.38 g/mol; density: 1.48 g/mL; bp: 61.7 C o
• 2-propanol (C3H8O): formula mass: 60.11 g/mol; density: 0.786 g/mL; bp: 82.4 C
1 ) What is the composition of this mixture on a mole percent basis? Show all calculations and report answer to correct number of significant figures
