The term "proof" is defined as twice the percent by volume of pure ethanol in solution. Thus, a solution that is 95% (by volume) ethanol is 190 proof. What is the molarity of ethanol in a 92 proof ethanol/water solution?
 
density of ethanol
= 0.80 g/cm3
 
density of water
= 1.0 g/cm3
 
mol. wt. of ethanol
= 46 g/mol
