**Calculation of Mass Percent of Acetic Acid**

**Objective:**
Determine the mass percent of acetic acid in a vinegar solution.

**Given Data:**
- Molar Mass of Acetic Acid: 60.05 g/mol
- Volume of Vinegar Solution: 5.00 mL
- Molarity of Solution: 0.322 M
- Density of Vinegar: 1.106 g/mL

**Hint:**
To find the mass percent of acetic acid, use the formula:

\[ \% \text{Acetic Acid} = \left( \frac{\text{Mass of acetic acid in sample}}{\text{Mass of vinegar sample}} \right) \times 100 \]

A value of 1.75 is shown, possibly representing the calculated mass percent.

**Explanation of the Process:**

1. **Calculate the Mass of Acetic Acid in the Sample:**
   - Use the molarity and molar mass to determine the grams of acetic acid.

2. **Calculate the Mass of the Vinegar Sample:**
   - Use the density and volume to find the total mass of the vinegar solution.

3. **Apply the Formula:**
   - Insert the calculated values into the formula to find the mass percent.

This provides an accurate understanding of the concentration of acetic acid in the vinegar solution.
