If a veterinarian instructs you to give 200 mg of medication and the concentration is 250 mg per 10 mL, how many mL should you give?

To determine the correct volume of medication to administer, first, we need to understand the concentration of the medication provided. The concentration is given as 250 mg per 10 mL, which indicates that in every 10 mL of the solution, there are 250 mg of the medication.

Next, we need to find out how many mL would contain the requested 200 mg of the medication. To do this, we can set up a proportion based on the concentration:

If 250 mg is contained in 10 mL, then to find out how much volume corresponds to 200 mg, we can use the following calculation:

1. First, find the amount of medication in 1 mL by dividing the concentration by the volume: [ 250 \text{ mg} / 10 \text{ mL} = 25 \text{ mg/mL} ]

2. Now, we can determine the volume needed to obtain 200 mg by dividing the desired mg by the concentration per mL: [ 200 \text{ mg} / 25 \text{ mg/mL} = 8 \text{ mL} ]

This calculation shows that to achieve a
