A mixture of 10 mL of benzene (MW= 78.11 g/mol, d=0.88 g/mL) and 50 mL of p-xylene (MW=106.17 g/mol, d=0.86 g/mL) is distilled.

Calculate the mole percent of each component, and using these mole percents and the figure below, answer the following questions:

1) What is the initial boiling point of this mixture?

2) What is the composition of the vapor in equilibrium with this liquid? What is the composition of the initial condensate from simple distillation?

3) Instead of simple distillation, you set up a fractional distillation. Assuming three threoretical plates, what is the composition of the first fration collected?

a start up company is trying to produce its own brand of antibacterial ointment. it decides to analyze a generic brand already on the market so that it can make suitable modification to the chemical composition. its known that the generic ointment contain benzoic acid( active ingredient), benzhydrol (the fixative) and anise, which add fragrance. you are a part of development team that wishes to separate these three substances in order to determine their relative proportions in the ointment, as well as to discover any inactive or unlisted constituents. some member of your team were able to isolate the inactive ingredient; However, NMR reveals that you still have a mixture of benzoic acid, benzhydrol, anisole left unseparated.

as a member of team, you have been asked to do the following:

1. design an experiment to separate the following compounds from a mixture using any combination of purification techniques (TLC, column chromatography, Extraction and recrystallization) 2. carry out characterization studies such as melting point, IR, NMR to confirm that your purification was successful.

3. determine the percent recovery of the individual components of the mixture.

mixture originally contained; 0.5g benzoic acid, 0.25g benzhydrol, 0.25ml anisole and 10ml diethyl ether.

1.Using your graphical data from part A, discuss the relationship between mass and volume. What is the significance of the slope of theline in your graph?

2.Discuss how you used the graph from part B to determine the composition of the unknown. How does increasing the amount of water in the mixture affect the density of the mixture? Why?

3.Suppose you were to determine the density of a solid and gas—how will the procedures and results differ from that of a liquid? Note: a good answer will address procedure differences between all three states of matter and will compare density results for all three states of matter.
