The average adult male has a total blood volume of 5.0 L

. After drinking a few beers, he has a BAC of 0.14. Blood alcohol concentration (BAC), is given in units of grams of alcohol per 100 mL of blood. What mass of alcohol is circulating in his blood?

1 answer

First, we need to calculate the amount of alcohol in grams present in 100 mL of blood at a BAC of 0.14.

BAC of 0.14 means 0.14 grams of alcohol per 100 mL of blood.

Since the total blood volume of the adult male is 5.0 L or 5000 mL, we can calculate the total mass of alcohol circulating in his blood:

Total mass of alcohol = BAC x Total blood volume
Total mass of alcohol = 0.14 g/100 mL x 5000 mL = 7 grams

Therefore, there are 7 grams of alcohol circulating in the adult male's blood after drinking a few beers.
