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.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

A) 0.46 M
B) 0.80 M
C) 0.92 M
D) 8.0 M
E) 17 M
