Explain mixing equal masses of water and ethanol

Reference no: EM13251389

At 63.5oC the vapor pressure of water is 175 torr and that of ethanol (C2H5OH) is 400 torr. A solution is made by mixing equal masses of water and ethanol.

a. What is the molality of ethanol in the solution?

b. What is the mole fraction of ethanol in the solution?

c. Assuming ideal solution behavior, what is the vapor pressure of the solution at 63.5oC?

d. What is the mole fraction of ethanol in the vapor above the solution?
