**Question 64 of 70**

**Chemistry Problem: Stoichiometry Calculation**

**Problem Statement:**
Determine the *moles of H₂* produced when *3.34 moles of HCl* reacts with Mg according to the following reaction:

\[ \text{Mg(s)} + \mathbf{2} \text{HCl(aq)} \rightarrow \text{MgCl}_2\text{(aq)} + \text{H}_2\text{(g)} \]

**Equation Layout:**

1. **Starting Amount:**
   - Empty slots available for input.

2. **Calculation Slots:**
   - Spaces provided for entering factors to complete the stoichiometry calculation.

**Options and Tools:**

- **Add Factor Buttons:**
  - Buttons with numerical values and units to assist in calculation: 
    - *2, 2.02, 1.67, 1, 24.31, 3.34, 0.835, 36.46*
  
- **Unit Buttons for Selection:**
  - Units include:
    - *mol MgCl₂, g/mol HCl, g MgCl₂, mol H₂, g/mol MgCl₂, mol Mg, g/mol H₂, mol HCl, g Mg, g HCl, g/mol Mg, g H₂*

- **Answer Slot:**
  - Slot provided to input or confirm the calculated answer.

- **Reset Button:**
  - Option to reset the calculation process.

This interactive tool aids in performing stoichiometric calculations by allowing users to input starting amounts, multiply by factors, and find the desired product quantity — in this case, the moles of hydrogen gas produced.
