ts) You measure out 16.7 mL of CS2 and dissolve it into 47.81 mL of C6H6 solvent. What is the mole fraction of CS2 in this solution? Potentially useful info: Molar masses: C6H6 = 78.11 g/mol. CS2 = 76.13 g/mol. The density of CS2 is 1.2632 g/mL. The density of C6H6 is 0.876 g/mL. The density of the solution made is 0.991 g/mL. (12 pts) You have a solute (XY) in CH3CH₂OH solvent. You add 0.496 moles of XY to 79.6 g of CH3CH₂OH. At what temperature, in °C, will this solution boil? Note: XY is known to ionize by 36.8% when it is placed in CH3CH₂OH. For CH3CH₂OH solvent: Molar mass= 46.07 g/mol, density = 0.7892 g/mL Kr= 1.22 °C/m Kb 1.99°C/m Freezing point is -114.6°C. Boiling point is 78.4°C.
