Answer:
Explanation:
Since we are not given the mole fraction of ethanol and water; we will solve this theoretically.
Using Raoult's Law:
For water:

where
of water = 12.5 mmHg
Then, the vapor pressure of water:

For ethanol:

and the
of ethanol = 32.1 mmHg
Then, the vapor pressure of ethanol:

The total vapor pressure 
The total vapor pressure =
