How many milligrams are present in a single 1.7 mL cartridge of a 3% solution?

Explanation:
In a local anesthetic solution, percent concentration tells you how many milligrams are in each milliliter. A 3% solution equals 3 g per 100 mL, which is 30 mg per 1 mL. Multiply by the cartridge volume: 30 mg/mL × 1.7 mL = 51 mg. So a 1.7 mL cartridge of a 3% solution contains 51 mg of the drug.
