**Problem Statement:**

An 819. g solution of Kool-Aid contains 721. g of water.

What is the mass percent of Kool-Aid mix in this solution?

[Input Box] %

Provide an answer in 3 significant figures.

---

**Explanation:**

To calculate the mass percent of Kool-Aid mix in the solution, you need to find the mass of the Kool-Aid mix and then use the formula for mass percent.

**Steps:**

1. **Determine the mass of the Kool-Aid mix:**
   - Total mass of the solution = 819 g
   - Mass of water = 721 g
   - Mass of Kool-Aid mix = Total mass - Mass of water

2. **Calculation:**
   - Mass of Kool-Aid mix = 819 g - 721 g = 98 g
   
3. **Mass Percent Formula:**

   \[
   \text{Mass Percent} = \left( \frac{\text{Mass of Kool-Aid mix}}{\text{Total mass of solution}} \right) \times 100
   \]

4. **Compute the mass percent:**

   \[
   \text{Mass Percent} = \left( \frac{98 \, \text{g}}{819 \, \text{g}} \right) \times 100 \approx 11.96\%
   \]

5. **Final answer:** 11.96% (rounded to 3 significant figures)
