![### Educational Exercise: Molarity and Solution Volume Calculation
#### Problem Statement
Determine the volume in liters (L) of a 0.724 M (molar) NaI (sodium iodide) solution required to contain 0.405 moles of NaI.
#### Calculation Interface Overview
1. **Equation Setup:**
- The interface allows you to set up the calculation using a dimensional analysis format.
- You begin with a "STARTING AMOUNT" section where you can input values.
2. **Factor and Calculation Structure:**
- The calculation process involves multiplying the starting amount by a conversion factor in parentheses to find the answer.
- The structure for inputs accommodates assigning known values, such as molarity and moles, to solve for volume.
3. **Input Fields and Buttons:**
- Numerical inputs available include 0.405, 0.724, and others.
- Buttons specify units or constants, like "mol NaI," "g NaI/mol," and "M NaI" to help guide correct factor placement.
- The section labeled "ANSWER" presents the calculated result.
- A "RESET" button allows clearing inputs for a new attempt.
#### Steps for Solving:
- Use the given molarity of the solution (0.724 M) and the moles of NaI (0.405 moles) to calculate the necessary volume in liters.
- Apply the formula:
\[
\text{Volume (L)} = \frac{\text{moles of solute}}{\text{molarity (M)}}
\]
\[
\text{Volume (L)} = \frac{0.405 \, \text{mol}}{0.724 \, \text{M}}
\]
This exercise applies basic concepts of solution chemistry, illustrating how to manipulate units for calculations involving molarity and volume.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Fa7127fdb-1b09-43df-9c21-7fe264d46fd8%2F3964d14b-7f2d-459c-89e7-09516f945558%2F1q8b54g_processed.png&w=3840&q=75)
