**Problem Statement:**

How many milliliters of water should a chemist add if they want to prepare a 0.200 M aqueous solution with 30.2 g of NaCl? Assume the density of the resulting solution is the same as the water.

**Description of Interface:**

1. **Equation Layout:**
   - A section is provided to enter the starting amount and factors needed for calculations. The format appears to be structured as:
     \[
     \text{Starting Amount} \times \left( \frac{\text{Factor 1}}{\text{Factor 2}} \right)
     \]

2. **Buttons for Inputs:**
   - The interface includes several buttons labeled with numbers and units for quick input:
     - Numerical values: 2580, 22.99, 2.58, 0.200, 0.517, 151, 1, 0.001, 1000, 58.44, 6.022 × 10²³, 30.2, 1.51 × 10⁵.
     - Units: mL, g NaCl/mol, mol NaCl, M NaCl, L, g NaCl.

3. **Additional Controls:**
   - Buttons for mathematical operations: multiplication (×) and parentheses ( ( ) ).
   - Answer section for submitting the solution.
   - Reset button to clear inputs and start over.

This interactive setup allows the user to input values and calculate the necessary amount of water to create their desired solution. The problem-solving process involves selecting the appropriate numerical and unit-based inputs to compute the solution using the given variables and constants.
