**Chemical Reaction Calculation Interface**

This interface is designed to calculate the amount of Na (sodium) solid required to completely react with a given volume of Cl₂ (chlorine) gas at standard temperature and pressure (STP). 

**Problem Statement:**
How many grams of Na solid are required to completely react with 19.2 L of Cl₂ gas at STP according to the following chemical reaction? Remember, 1 mol of an ideal gas has a volume of 22.4 L at STP.

**Chemical Equation:**
\[ 2 \text{Na(s)} + \text{Cl}_2\text{(g)} \rightarrow 2 \text{NaCl(s)} \]

**Interface Components:**

- **Starting Amount**: Section for entering the initial amount of reactants.

- **Calculation Area**: 
  - The problem involves using the stoichiometric relationship from the balanced chemical equation.
  - An equation box allows you to input various conversion factors based on molar ratios, volumes, and molar masses.
  
- **Buttons for Input Values**: 
  - Numerical values such as 68.90, 2, 22.99 (molar mass of Na), 30.4, 0.0373, 0.857, 1.71, and others for performing calculations through factor multiplications.
  - Constants: \(6.022 \times 10^{23}\) for Avogadro’s number and 35.45 (for Cl).

- **Answer Box**: The calculated result area.

- **Reset Button**: To clear inputs and start over.

This educational tool illustrates practical chemistry calculations using stoichiometry and conversions for ideal gases at STP.
