Given l calorie = 4184 joules (exact), convert 75.6 joules to kilocalories. 3. Given 1 kilometer 0.621 miles (measured), convert a speed of 55 mi/hr (commonly abbreviated mph) to km/hr. 4. Given 1 kilogram (kg) - 2.20 lb. Suppose the dosage for a medication is specified as 5.0 mg/kg body weight, how much medication must be administered to a 175 Ib patient? 19)Explanation / Answer
1.
760 torr = 1 atm
725 torr = 1 * 725 / 760 = 0.954 atm
2.
4.184 J = 1 cal
75.6 J = 75.6 * 1 / 4.184 cal = 18.1 cal = 0.0181 kcal
3.
0.621 mile = 1 km
55 mile / hr = 55 * 1 / 0.621 km/hr = 88.6 km/hr
4.
2.20 lb = 1 kg
175 lb = 175 * 1 / 2.20 kg = 79.5 kg.
1 kg. of body weight = 5 .0 mg of medication
then, 79.5 kg of body weight = 79.5 * 5.0 = 397.7 mg.
