The correct answer is: 2

To determine how many drinks a vodka on the rocks containing 3 ounces of 80 proof vodka should count as, it's essential to understand the conversion of alcohol measurements into standard drink equivalents. A standard drink in the United States typically contains about 0.6 ounces of pure alcohol. Since 80 proof vodka is 40% alcohol by volume, a 1-ounce serving contains 0.4 ounces of pure alcohol. Therefore, 3 ounces of 80 proof vodka contains 1.2 ounces of pure alcohol (calculated as 3 ounces x 0.4). To find out how many standard drinks this amount represents, divide the total ounces of pure alcohol (1.2 ounces) by the amount in a standard drink (0.6 ounces). This calculation results in 2 standard drinks (1.2 ounces / 0.6 ounces). This conversion is crucial in a bartending and responsible serving context, as it helps servers understand how much alcohol is being served to patrons and ensures that they adhere to legal serving limits and promote responsible drinking.
