BAC is defined as the number of grams of alcohol found in how many milliliters of blood?

• A. 50
• B. 100
• C. 200
• D. 500

Answer: (B)

BAC is the amount of ethanol measured in a fixed volume of blood, specifically in grams per 100 milliliters of blood. This standard (grams per 100 mL, or g/dL) lets doctors and law enforcement compare levels consistently across people and tests. So, the definition uses 100 milliliters as the reference volume. For example, a BAC of 0.08 means 0.08 grams of ethanol in each 100 mL of blood. The other volumes (50, 200, or 500 milliliters) aren’t the standard reference, which is why 100 milliliters is the correct choice.
