milliliter(s)
(simplify your answer. type an integer or decimal rounded to the nearest

Explanation:

Step1: Set up the proportion

Use the formula \( \text{Volume (mL)}=\frac{\text{Dose ordered (mg)}}{\text{Dose available (mg/mL)}}\). Here, the dose ordered is \(450\) mg and the dose available is \(325\) mg/mL. So the formula becomes \(V=\frac{450}{325}\).

Step2: Calculate the value

\(V = \frac{450}{325}=\frac{90}{65}=\frac{18}{13}\approx1.3846\)

Answer:

\(1.4\)
