Answer: 20 ounces

To solve this question, you need to convert the unit multiple times.

Pseudoephedrine elixir contains 30 milligrams per teaspoon and its sales limited to 3.6grams daily. If 1 ounce equal to 6 teaspoons, then 3.6gram will be equal to:

3.6 grams * (1000mg/gram) / (30 mg/teaspoon) / (6 teaspoon/ounce) = 20 ounces
