**Stoichiometry Calculation for Aluminum and Sulfuric Acid Reaction**

**Objective**: Determine how many moles of \( \text{H}_2\text{SO}_4 \) are required to completely react with 7.20 moles of \( \text{Al} \) according to the balanced chemical reaction.

**Balanced Chemical Equation**:
\[ 
2 \text{Al(s)} + 3 \text{H}_2\text{SO}_4 \text{(aq)} \rightarrow \text{Al}_2(\text{SO}_4)_3 \text{(aq)} + 3 \text{H}_2 \text{(g)} 
\]

**Starting Amount**:
\[ 
7.20 \, \text{mol} \, \text{Al} 
\]

**Calculation**:
\[ 
7.20 \, \text{mol} \, \text{Al} \times \left( \frac{\text{unknown}}{\text{unknown}} \right) = \, \text{mol} \, \text{H}_2\text{SO}_4 
\]

**Interactive Elements**:
