What is the concentration of amoxicillin oral suspension (250 mg/5 mL) in mg per mL?

Explanation:
Concentration equals the amount of drug per unit volume. To get mg per mL, divide the total amount of drug by the total volume: 250 mg in 5 mL gives 250 ÷ 5 = 50 mg per 1 mL. So the suspension is 50 mg/mL. For context, 1 mL contains about 50 mg, 10 mL would contain about 500 mg, and multiplying 50 mg/mL by 5 mL returns the original 250 mg, confirming the calculation.
