A martini, weighing about 5.0 oz (142 g), contains 30.0% by mass of alcohol. About 15% of the alcohol in the martini passes directly into the bloodstream (7.0 L for an adult). Estimate the concentration of alcohol in the blood (g/cm3) of a person who drinks two martinis before dinner. (A concentration of 0.00080 g/cm3 or more is frequently considered indicative of intoxication in a normal adult.)
