The vapor pressure of ethanol (CH3CH2OH) at 20ºC is 44 mmHg, and the vapor pressure of methanol (CH3OH) at the same temperature is 94 mm Hg. A mixture of 35.0 g of methanol and 45.0 g of ethanol is prepared and can be assumed to behave ideally. Answer the following questions concerning the mixture. (You must show all your work)
1) Which component is more volatile?
2) Determine the mole fraction of both components of the liquid mixture.
3) Calculate the vapor pressure of methanol and ethanol above the solution.
4) Calculatet the total vapor pressure.
5) What is the mole fraction of each component in the vapor phase.
6) What method can be used to separate the 2 components from one another?
7) Specifically describe how the ethanol and methanol will be separated by this method? Be sure to address which component would be collected and which one would be left behind.
8) Sketch a simple apparatus that could be used to separate this mixture with the method described above.
