### Concentration of Caffeine in Coca-Cola #### d) What is the concentration of caffeine in Coke in ppm? To convert the caffeine content in Coca-Cola to parts per million (ppm), you must know the amount of caffeine in milligrams per liter (mg/L) and understand that 1 ppm is equivalent to 1 mg/L. #### e) What is the concentration of caffeine in Coke in ppb? To express the caffeine concentration in parts per billion (ppb), you can multiply the ppm value by 1,000, since 1 ppm equals 1,000 ppb. #### f) How many pounds (lb) of caffeine are in a liter (L) of Coke? To convert the caffeine content from milligrams or grams to pounds, you'll need an appropriate conversion factor. Note that: - 1 pound = 453.592 grams You'll first want to convert the milligrams to grams, and then convert grams to pounds. Remember to look up the conversion items you need for accuracy.
