  B A C ( Blood Alcohol Content ) of 0.10 means that there are 0.10 g of alcohol for every  dl  of blood.
  5 L = 50 dl
  50 * 0.10 g = 5 g
  In his blood is circulating 5 grams of alcohol. 

Answer:5 grams  of alcohol is circulating in his blood

BAC (Blood alcohol content) means that level of alcohol in the blood stream.

Given BAC of an adult male = 0.10 = 0.10 g/100 ml

Total blood volume = 5 L = 5000 ml

MAss of alcohol in 5000 ml of blood:

[tex]\frac{0.10 g}{100 ml}\times 5000 ml=5 g[/tex]

5 grams  of alcohol is circulating in his blood
