Richard has a bottle of cold medicine that contains 500 mg of the active ingredient, acetaminophen. The bottle contains 100 ml of syrup. Richard's doctor prescribed 20 mg of acetaminophen. How many doses does the bottle contain? How much syrup is in each dose?
Since there are 500 mg available in one bottle, we will first calculate to find out how many doses are in each bottle. Following his prescription, Richard needs 20mg per dose. We will divide 500mg/btl by 20mg/dose, leaving us with 25 doses/bottle. Now that we know there are 25 doses within one bottle, the amount of syrup per dose is figured by dividing the number of ml/btl by dose/btl. 100ml/btl divided by 25 dose/btl= 4 ml/dose.
