Question

**Concentration Practice Problems**

1. One can of Coke holds 355 mL of soda and contains 34 mg of caffeine.

### 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.
