Solution Concentration — Definition & Overview

The amount of ethyl alcohol in an alcoholic drink is typically expressed in percent ABV (alcohol by volume) or proof, where $1\% \text{ ABV} \approx 2\text{ proof}$. If ethyl alcohol has a density of $0.789 \text{ } \frac{g}{mL}$ and a molar mass of $46.07 \text{ } \frac{g}{mol}$, what is the molarity of 80 proof vodka?
