You want to compare a patient's measured calcium ion concentration to the normal calcium ion concentration in blood serum. The only range you can find is 4.5 - 5.5 mEq/L, but the blood results show a concentration of 0.22 mmol/dL. Convert the measured calcium ion concentration from the blood results to mEq/L (to one decimal place). What are the units?

Chlorine is used to disinfect swimming pools. The accepted concentration for this purpose is 1 ppm chlorine or 1 g of chlorine per million g of water. Calculate the volume of a chlorine solution (in milliliters) a homeowner should add to her swimming pool to achieve 1.00 ppm chlorine if the solution contains 6.00 percent chlorine by mass and there are 6.63 ×104 gallons of water in the pool. (1 gallon = 3.79 L; density of liquids = 1.00 g/mL.)

Nurses are often required to calculate dosages. That is, they must check the order that a doctor has given for the administration of a drug and decide whether the dosage is correct. To calculate correctly they must convert between different metric units. For example, 1,000 milligrams (mg) = 1 gram (g); and 1,000 micrograms (mcg) = 1 mg. - Suppose a doctor has ordered a dose of 0.1 gram of a medication. The drug comes in a solution concentration of 300 mg per milliliter. How many milliliters of this solution is required?
