The Term "Proof" Is Defined as Twice the Percent by Volume

Multiple Choice

The term "proof" is defined as twice the percent by volume of pure ethanol in solution. A solution that is 95% ethanol is 190 proof. What is the molarity of ethanol in a 92-proof ethanol/water solution (Given: density of ethanol = 0.80 g/cm³; density of water = 1.0 g/cm³)

A) 8.8 M
B) 8.4 M
C) 8.2 M
D) 8.0 M
E) None of the above
