**Question:**  
What is the mass percent of Na₂SO₄ in a solution made by dissolving 16.0 g Na₂SO₄ in 232.0 g H₂O?

---

**Calculation Box:**  
[Text box for input]

% Na₂SO₄ solution

---

**Explanation:**  
This question asks for the mass percent concentration of sodium sulfate (Na₂SO₄) in a solution. To find this, you divide the mass of the solute (Na₂SO₄) by the total mass of the solution and multiply by 100 to get a percentage. 

**Formula:**  
\[ \text{Mass percent} = \left( \frac{\text{mass of Na}_2\text{SO}_4}{\text{mass of Na}_2\text{SO}_4 + \text{mass of H}_2\text{O}} \right) \times 100 \]

Expert Solution
Step 1: Given information:

The mass of solute open parentheses Na subscript 2 SO subscript 4 close parentheses = 16.0 g

The mass of solvent open parentheses straight H subscript 2 straight O close parentheses = 232.0 g

The mass percent of Na subscript 2 SO subscript 4 = ?
