### Stoichiometry Practice Problems

Below is a series of stoichiometry practice problems related to the chemical reaction between sodium hydroxide (NaOH) and sulfuric acid (H₂SO₄). The balanced chemical equation for this reaction is as follows:

\[ 2 \text{NaOH} (aq) + \text{H}_2\text{SO}_4 (aq) \rightarrow \text{Na}_2\text{SO}_4 (aq) + 2 \text{H}_2\text{O} (l) \]

#### Problem (a)
**Question:**
Calculate the moles of Na₂SO₄ produced from 4.0 mol H₂SO₄.

**Input:**
\[ \_\_\_\_\_\_\_\_ \text{mol Na}_2\text{SO}_4 \]

**Tolerance:**
±2%

#### Problem (b)
**Question:**
Calculate the moles of H₂O produced from 0.041 mol NaOH.

**Input:**
\[ \_\_\_\_\_\_\_\_ \text{mol H}_2\text{O} \]

**Tolerance:**
