### Boron Isotopes: Natural Occurrence and Mass

There are only two naturally occurring stable isotopes of boron, the masses of which are listed in the table below. Use whatever data you need from the ALEKS Periodic Table to calculate the natural abundance of each isotope and complete the table.

**Ensure your answers have the correct number of significant digits.**

| Isotope | Mass (amu) | Natural Abundance (%) |
|---------|------------|-----------------------|
| \( ^{10}\text{B} \)  | 10.013     |                       |
| \( ^{11}\text{B} \)  | 11.009     |                       |

**Tasks:**

1. Calculate the natural abundance of \( ^{10}\text{B} \) and \( ^{11}\text{B} \).
2. Input the calculated values in the appropriate fields.

**Instructions for Calculation:**
- Use the given mass values and reference the periodic table for required data such as average atomic mass.
- Apply the concepts of atomic mass unit calculations and isotope abundance to find natural abundance percentages.

**Note:**
Ensure accuracy in calculations by using the appropriate number of significant figures as specified in scientific guidelines.
