Question
An 80 -proof brandy is a $40 . \%$ (v/v) ethanol solution. The "proof" is twice the percent concentration of alcohol in the beverage. How many milliliters of alcohol are present in 750 mL of brandy? (9.4)

An 80 proof brandy is 40.0% (v/v) ethyl alcohol. The "proof" is twice the percent concentration of alcohol in the beverage. How many milliliters of alcohol are present in 720 mL of brandy?
The alcohol content of hard liquor is normally given in terms of the "proof," which is defined as twice the percentage by volume of ethanol $\left(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}\right)$ present. Calculate the number of grams of alcohol present in $1.00 \mathrm{L}$ of 75 -proof gin. The density of ethanol is $0.798 \mathrm{g} / \mathrm{mL}$.
