How much pure alcohol is contained in a 12 oz beer with 4% alcohol?

To calculate the amount of pure alcohol in a 12 oz beer with 4% alcohol by volume (ABV), you can use the formula:

Amount of pure alcohol (in oz) = Volume of beverage (in oz) x Alcohol by volume (as a decimal)

First, convert the percentage to a decimal: 4% becomes 0.04. Then, multiply the volume of the beer (12 oz) by the ABV (0.04):

Amount of pure alcohol = 12 oz x 0.04 = 0.48 oz

This calculation shows that there are 0.48 ounces of pure alcohol in a 12 oz beer with 4% alcohol. This means that the option indicating 0.48 oz is the correct answer, as it accurately represents the volume of pure alcohol present in the beverage based on its given ABV and total volume.
