How many milliliters are required to deliver 25 mg of a medication at a strength of 5%?

To determine how many milliliters are required to deliver 25 mg of a medication at a strength of 5%, you first need to understand that a 5% solution means there are 5 grams of medication in 100 mL of solution.

Since the question involves milligrams and the solution is given in grams, it's essential to convert grams to milligrams for consistency. Specifically, 5 grams is equal to 5,000 milligrams. Therefore, in 100 mL of a 5% solution, there are 5,000 mg of the medication.

Next, to find out how many milligrams are in 1 mL of the 5% solution, you divide the total milligrams by the total volume:

5,000 mg / 100 mL = 50 mg/mL.

Now, to find out how many milliliters are needed to achieve a dose of 25 mg, you can set up a proportion where you need to calculate the volume that contains the desired amount of medication:

25 mg × (1 mL / 50 mg) = 0.5 mL.

This calculation shows that you need 0.5 mL of the 5% medication solution to deliver the
