Final answer:
Blood Alcohol Concentration is expressed in terms of grams of alcohol per 100 b. liters of blood.
Explanation:
Blood Alcohol Concentration (BAC) is expressed in terms of grams of alcohol per 100 milliliters of blood. This measurement is used to determine the level of alcohol in a person's bloodstream and is typically expressed as a percentage. For example, a BAC of 0.08% means that there are 0.08 grams of alcohol per 100 milliliters of blood.
To calculate BAC, the amount of alcohol consumed is divided by the total body water, which is typically estimated based on factors like gender and weight. Since alcohol is distributed in the body's water, BAC is affected by the amount of water in the body. Women generally have a higher BAC than men after consuming the same amount of alcohol due to differences in body composition.
b. The legal BAC limit for driving varies by country but is often set around 0.08%. Exceeding this limit can result in legal penalties, as alcohol impairs judgment, coordination, and reaction time, increasing the risk of accidents. It's important to note that BAC can continue to rise even after drinking stops, peaking around 30-90 minutes after the last drink.
