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?
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.
