Solution

Solution Steps

Step 1: Understand the Problem

The problem asks us to determine how many milliliters of a solution are needed to provide a specific dose of atropine. The ordered dose is 0.50 mg, and the concentration of the solution is 0.10 mg/mL.

Step 2: Set Up the Equation

To find the volume in milliliters, we can use the formula:

\[ \text{Volume (mL)} = \frac{\text{Dose (mg)}}{\text{Concentration (mg/mL)}} \]

Step 3: Substitute the Values

Substitute the given values into the equation:

\[ \text{Volume (mL)} = \frac{0.50 \, \text{mg}}{0.10 \, \text{mg/mL}} \]

Step 4: Calculate the Volume

Perform the division to find the volume:

\[ \text{Volume (mL)} = \frac{0.50}{0.10} = 5.0 \, \text{mL} \]
