Reference no: EM132431843

Problem: A solution is made by mixing 25.0 mL of ethanol (density 0.798 g/mL, molar mass 46.0 g) and 75.0 mL of water (density 1.00 g/mL, molar mass 18.0 g).

Required:

Question 1: What is the mass percent (m/m) of ethanol in this mixture?

Question 2: What are the mole fractions of both ethanol and water in this mixture?

Question 3: What is the vapor pressure of the mixture, in torr, at 25o? ?C if the vapor pressure of water is 23.8 torr and the vapor pressure of ethanol is 59.2 torr??

Question 4: What is the molality of this solution??
