Question

A 125-mL container of amoxicillin contains 600 mg/5 mL. How many milliliters would be used to administer 400 mg of amoxicillin?

Answer 1

Answer:

3.33 milliliters.

Step-by-step explanation:

We have been given that a 125-mL container of amoxicillin contains 600 mg/5 mL.

First of all, we will find amount of mg's of amoxicillin per ml as:

$\text{Concentration of amoxicillin per ml}=\frac{\text{600 mg}}{\text{5 ml}}$

$\text{Concentration of amoxicillin per ml}=\frac{\text{120 mg}}{\text{ml}}$

Now, we will use proportions as:

$\frac{\text{1 ml}}{\text{120 mg}}=\frac{x}{\text{400 mg}}$

$\frac{\text{1 ml}}{\text{120 mg}}\times \text{400 mg}=\frac{x}{\text{400 mg}}\times \text{400 mg}$

$\frac{\text{400 ml}}{120 }=x$

$\text{3.33 ml}=x$

Therefore, 3.33 milliliters would be used to administer 400 mg of amoxicillin.
