**Determining the Atomic Mass of Potassium:**

To determine the atomic mass of potassium, given the information about potassium's stable isotopes:

| Isotope | Mass               | Percent Abundance |
|---------|--------------------|-------------------|
| K-39    | 38.96370 amu       | 93.258%           |
| K-41    | 40.96183 amu       | 6.730%            |

**Step-by-Step Calculation Process:**

**Step 1: Select the appropriate mathematical steps.**

Here are the math steps you need to perform for this calculation correctly:

1. **Multiply the mass of each isotope by its percent abundance (as a decimal):**

   - For K-39: \(38.96370 \, \text{amu} \times 0.93258\)
   - For K-41: \(40.96183 \, \text{amu} \times 0.06730\)

2. **Sum the results of these multiplications to get the average atomic mass of potassium:**

   - \((38.96370 \, \text{amu} \times 0.93258) + (40.96183 \, \text{amu} \times 0.06730)\)

The steps are visually represented in the following options:

- \(38.96370 \, \text{amu} \times 0.93258\)
- \(40.96183 \, \text{amu} \times 0.06730\)

**Step 2: Perform the Calculation and Enter the Answer**

Now, calculate the result using the selected steps:

1. Calculate the individual products:
   - For K-39: \(38.96370 \, \text{amu} \times 0.93258 = 36.34308 \, \text{amu}\)
   - For K-41: \(40.96183 \, \text{amu} \times 0.06730 = 2.75568 \, \text{amu}\)

2. Add the results:
   - \(36.34308 \, \text{amu} + 2.75568 \, \text{amu} = 39.09876 \, \text{amu}\)

**Next, perform the calculation and enter your numerical answer here.**
   
\[ \boxed{39.
