Question

It has been reported that for the average drinker, the consumption of 44 g of pure alcohol, taken as either 90 mL of whiskey or 155 mL of martini, results in an average alcohol concentration in the blood of 0.08 g/100 mL of blood. If the total volume of blood in a human adult is 7.0 L, what percentage of the ingested alcohol is in the blood?

Answer 1

Let’s calculate the percentage of ingested alcohol that is in the blood. If the average alcohol concentration in the blood is 0.08 g/100 mL of blood, then for a total blood volume of 7.0 L (or 7000 mL), the total amount of alcohol in the blood would be 0.08 g/100 mL * 7000 mL = 5.6 g.

Since the consumption of 44 g of pure alcohol results in an average alcohol concentration of 0.08 g/100 mL of blood, the percentage of ingested alcohol that is in the blood would be (5.6 g / 44 g) * 100% = 12.7%.
