Amoxicillin 50 mg order. The vial concentration is 125 mg per 5 mL. How many milliliters should be drawn?

Dose calculation using concentration and unit conversion. The vial provides 125 mg in 5 mL, which is 25 mg per 1 mL. To deliver 50 mg, you need 50 mg ÷ 25 mg/mL = 2 mL. Another way to see it is with a proportion: 125 mg/5 mL = 50 mg/x mL, so x = (50 × 5) / 125 = 2 mL. The volume to draw is 2 mL. Always check units so you’re using the correct concentration to convert mg to mL.
