If a medication concentration is 10 milligrams per 5 milliliters, how many milliliters should be given to an animal that needs 5 milligrams?

To determine the correct volume of medication to administer, you can use a basic proportion based on the concentration provided. The concentration tells you that there are 10 milligrams of medication in 5 milliliters. This means that for every 10 milligrams, you have a corresponding volume of 5 milliliters.

To find out how many milliliters are needed for a dose of 5 milligrams, you can set up a ratio. If you have the total concentration of 10 milligrams in 5 milliliters, then:

• For 5 milligrams, you would need to calculate the proportionate amount of milliliters.

Using a straightforward calculation, you can set up a direct ratio:

5 mg (desired dose) / 10 mg (in concentration) = x mL / 5 mL (corresponding volume)

By cross-multiplying, you get:

5 mg * 5 mL = 10 mg * x mL

This simplifies to:

25 = 10x

Now, divide both sides by 10:

x = 2.5 mL

Thus, to achieve a dose of 5 milligrams, you need to administer 2.5 milliliters
