How many cubic centimeters are there in 200 milliliters? 4. Assume a pill has a dosage of 350 mg of medication. How much medication is this in grams?Explanation / Answer
1. The scientific discipline that studies the function of human body is known as PHYSIOLOGY
2a. Base unit of length in metric system = Meter
2b. Base unit of volume in metric system = Cubic meter
3. 1 cubic Centimeter = 1 mL. So, 200 cc = 200 mL
4. 1 g = 1000 mg. 1 mg = 0.001 g. So, 350 mg = 0.35 g.
5. 0.000345 = 3.45 X 10-4
6. 1 kg = 1000 g = 1000 X 1000 mg. So, 4.5 kg = 4.5 X 106 mg
7. 1 m = 1000 mm. 1 mm = 0.001 m. So, 250 mm = 0.25 m
8. 1/10000 = 0.0001 = 1.0 x 10-4
9a. 1/1000 sec = 10-3 sec = 1 millisec
9b. 1000 L
9c. 1/100 m = 0.01 m = 1 cm
