1. When brought to the emergency room, an accident victim has 3 liters of blood and is still losing blood at arate of 0.25 liters per hour. He is immediately given continuous blood transfusions at 0.5 liters per hour, andan antibiotic drug is administered intravenously at 0.5 grams per hour. Four hours later, the bleeding hasstopped but the transfusions continue for an additional two hours. Determine the amount of the antibioticin the patient's blood at the time that the transfusions stop.
