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

Explanation:

Step1: Set up the proportion

Use the formula \( \text{Volume (V)}=\frac{\text{Dose ordered (D)}}{\text{Dose on hand (H)}}\times\text{Quantity (Q)}\). Here, \(D = 22.5\) mg, \(H=45\) mg, and \(Q = 1\) mL.

Step2: Calculate the volume

Substitute the values into the formula: \(V=\frac{22.5}{45}\times1\).
