The term proof is defined as twice the percent by volume of pure ethanol in solution
Chapter 11, Problem 11.121(choose chapter or problem)
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 ethanolwater solution? Assume the density of ethanol, C2H5OH, is 0.79 g/cm3 and the density of water is 1.0 g/cm3
