A typical martini glass weighs 5.0 oz (142g) as well as the alcohol content is 30% by mass. About 15% of the alcohol in the martini passes directly into the bloodstream blood volume = 7.0 L in an adult. Regard as an adult who drinks two martinis with lunch. Approximate the blood alcohol concentration in this person after two martinis have been consumed an adult with a blood alcohol concentration of 3.0 X 10 (-3) g/mL or more is considered intoxicated. Is this person intoxicated?
