The ethanol content of alcoholic beverages is sometimes
expressed in terms of “proof.” This term comes from a 17th century
test for the alcohol content in whiskey. The whiskey was poured
onto gunpowder and then set on fire. If the whiskey was too wet,
the gunpowder would not ignite after the whiskey had burned off.
However, if the whiskey had not been watered down, the gunpowder
would ignite. A positive test required a minimum ethanol content of
approximately 50% ethanol...

A vapor composed of 0.65 mole fraction ethanol and 0.35 mole
fraction acetic acid at 120.0 mmHg (absolute), is in equilibrium
with a liquid phase also composed of ethanol and acetic acid.
Assume that the liquid is an ideal solution and apply Raoult's law
to find the following.
What is the temperature of the liquid____oC?
What are the mole fractions of the liquid pahse?
XE=___mol ethanol/mol
XA=___ mol acetic acid/mol

How much energy per mole is required to transfer acetic acid, a
byproduct of ethanol metabolism from blood to urine. The relevant
concentrations are 39.00 and 742.00 ppm respectively and you are
running a fever at 39oC. State your answer in kJ/mol. (Donnan
Potential Question)
EDIT: ITS ASKING FOR HOW MUCH ENERGY IN KJ/MOL IS NEEDED TO
TRANSPORT ACETIC ACID FROM BLOOD TO URINE.
