What is the concentration of the medication per milliliter?

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

Answer: (A)

Concentration is the amount of medication in each milliliter of solution. You find it by dividing the total amount of drug (in milligrams) by the total volume of solution (in milliliters). The problem’s data give a ratio that equals 15 mg per milliliter. For example, if you had 45 mg in 3 mL, the calculation would be 45 mg ÷ 3 mL = 15 mg/mL. The other values would require different total doses or volumes, so they don’t match the given data.
