A patient needs 750 mg of Amoxicillin, and the pharmacy has a concentration of 50 mg/mL. How many milliliters are needed?

To determine how many milliliters of Amoxicillin are needed for a dosage of 750 mg when the concentration available is 50 mg/mL, you can use the formula:

[ \text{Volume (mL)} = \frac{\text{Dosage (mg)}}{\text{Concentration (mg/mL)}} ]

Substituting the values:

[ \text{Volume (mL)} = \frac{750 \text{ mg}}{50 \text{ mg/mL}} ]

This calculation simplifies to:

[ \text{Volume (mL)} = 15 \text{ mL} ]

Therefore, the correct answer is 15 mL. This concludes that you will need to measure out 15 mL of the Amoxicillin solution to meet the required dose of 750 mg. This is essential for ensuring that patients receive the correct amount of medication for effective treatment.
