How much medicine is in 1 mL?

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

Answer: (B)

Knowing how much medicine is in 1 mL depends on the concentration, which is the amount of drug per unit volume (mg per mL). The dose in a given volume is found by multiplying the concentration by the volume: mg = (mg per mL) × (mL). So for 1 mL, you just take the concentration value. If the label says 15 mg per 1 mL, then exactly 15 mg are in 1 mL. If it were 10 mg/mL, 1 mL would contain 10 mg, and if it were 20 mg/mL, 1 mL would contain 20 mg. The important point is you need the concentration to convert volume to mass. In this case, 1 mL contains 15 mg because the concentration is 15 mg per mL.
