If a dose of 200 mg of a medication is diluted in 10 mL of water, what is the concentration in mg/mL?

To determine the concentration of the medication in mg/mL, you need to divide the total amount of the medication by the total volume of the solution. In this scenario, you have 200 mg of medication diluted in 10 mL of water.

The calculation is performed as follows:

Concentration (mg/mL) = Total amount of medication (mg) / Total volume of solution (mL)

Inserting the known values gives:

Concentration = 200 mg / 10 mL = 20 mg/mL

Thus, the concentration of the medication is correctly calculated as 20 mg/mL. This reflects the strength of the solution, indicating that for every milliliter of the solution, there are 20 milligrams of the medication present. This understanding is crucial for safe medication administration and ensuring patients receive the proper dosage.
