Which statement correctly describes the product's concentration?

• A. 15 mg per mL
• B. 5 mg per mL
• C. 10 mg per mL
• D. 20 mg per mL

Answer: (A)

Concentration is how much drug is present in each milliliter of solution. You find it by dividing the total number of milligrams by the total milliliters: mg/mL = total mg ÷ total mL. If the product’s label or given data shows a total amount and a total volume that, when divided, equals 15 mg per mL, that is the stated concentration. For example, 150 mg in 10 mL or 300 mg in 20 mL both yield 15 mg/mL. The other options would only be correct if the container actually contained those totals, which would contradict the given label. So describing the product as 15 mg per mL matches the rated strength of the solution.
