An individual's blood alcohol content (% alcohol in blood as measured mass per volume = mass of alcohol per volume of blood) was 0.15. If we assume the individual drank all of the alcohol at once (i.e. no metabolism of alcohol by the body), the total volume of blood for the individual was 1.5 gallons, and the individual was drinking Maker's Mark (130 proof), what volume of Maker's Mark was consumed?
