Macmillan Learning At a resting pulse rate of 79 beats per minute, the human heart typically pumps about 69 mL of blood per beat. Blood has a density of 1060 kg/m . Circulating all of the blood in the body through the heart takes about 1 min for a person at rest. Approximately how much blood is in the body? volume of blood in body: On average, what mass of blood does the heart pump with each heart beat? mass per heart beat: m³ 3 kg
1. A farmer needs to administer a dose of albendazole dewormer to a cow that weighs 992 lbs. The dosage recommended by his veterinarian is 10 mg per kg of body weight. How many mg of albendazole should the farmer administer? [1 kg = 2.205 lbs] Calculate the weight of this cow in kg. Round to 4 decimal places. Then, using the exact weight in kg (not your rounded weight) and the medical conversion, determine the dose that the cow should get in mg. Round to two decimal places.Using your answer from the previous slide, if albendazole is only available as a liquid, and each milliliter of the liquid contains 125 mg of albendazole, how many mL of the liquid should the farmer administer?
