The setup
For liquids, the quantity is the volume that contains the dose on hand, such as 125 mg per 5 mL.
250 mg ÷ 125 mg × 5 mL = 10 mL
Units
Answers are always in mL. This practice does not use cc, teaspoons, or tablespoons.
Rounding
If an answer needs rounding, the question tells you exactly how (for example, “Round the final answer to the nearest tenth.”). Round only the final answer, never the steps in between. If there is no instruction, the answer is exact.
