Question

A solution of the strength of 25 mg per mL is to be used to prepare a dosage of 300mg for a patient. How many mL of solution will be needed?

Answer 1

Let's review the information provided to answer the execise correctly:

Strength of the solution = 25 mg per mL

Dosage to prepare = 300 mL

Now, let's answer the question, as follows:

Amount of solution needed = Dosage to prepare/Strength of the solution

Substituting with the values we know:

Amount of solution needed = 300/25

Amount of solution needed = 12 mL

Interpretation

We need 12 mL of solution for a dosage of 300 mg of strength for the patient
