If a medication has a concentration of 1.5 g in 100 mL, what is the concentration in mg/mL?

To determine the concentration of the medication in mg/mL, it is important to perform the necessary conversion from grams to milligrams and adjust the measurement per milliliter accordingly.

The medication concentration is given as 1.5 grams in 100 mL. To convert grams to milligrams, the conversion factor used is that 1 gram equals 1000 milligrams. Thus, 1.5 grams can be converted to milligrams as follows:

1.5 grams × 1000 mg/g = 1500 mg.

Now that the total amount of the medication is established as 1500 mg in 100 mL, the next step is to find out how many milligrams there are in 1 mL. This requires dividing the total amount of medication by the volume in milliliters:

1500 mg ÷ 100 mL = 15 mg/mL.

This calculation clearly shows that the concentration of the medication is 15 mg/mL. Therefore, the correct answer is 15 mg/mL, which corresponds to the selection provided. Understanding these conversions and calculations is crucial in medical settings to ensure accurate dosing and effective patient care.
