If you have a medication with a concentration of 300 mg/5 mL, what is the concentration in mg/mL?

If you have a medication with a concentration of 300 mg/5 mL, what is the concentration in mg/mL?

• A. 30 mg/mL
• B. 60 mg/mL
• C. 90 mg/mL
• D. 150 mg/mL

Answer: (B)

To convert the concentration of the medication from mg per a given volume (mg/5 mL) to mg per mL, a simple calculation is required. The concentration given is 300 mg in 5 mL. To find the concentration in mg/mL, you divide the total amount of the medication by the total volume: 300 mg ÷ 5 mL = 60 mg/mL. Thus, the concentration of the medication is indeed 60 mg/mL. This method of conversion—taking the total quantity of the substance and dividing it by the volume in which it is dissolved or contained—is a fundamental skill in dosage calculation, allowing healthcare professionals to accurately understand and administer medications based on concentration.
