Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Question

### Iron and Chlorine Reaction: Percent Yield Calculation

**Problem Statement:**
Iron metal reacts with chlorine gas, giving iron(III) chloride. The balanced chemical equation for this reaction is:
\[ 2 \, \text{Fe} (s) + 3 \, \text{Cl}_2 (g) \rightarrow 2 \, \text{FeCl}_3 (s) \]

**Question:**
If only 16.1 g of FeCl\(_3\) is obtained from 32.0 g of iron and excess Cl\(_2\), what is the percent yield?

**Solution Framework:**

To calculate the percent yield, follow these steps:

1. **Determine the Molar Masses:**
- Molar mass of Fe (iron): \( 55.85 \, \text{g/mol} \)
- Molar mass of FeCl\(_3\):
- Fe: \( 55.85 \, \text{g/mol} \)
- Cl: \( 35.45 \, \text{g/mol} \) (since there are three Cl atoms, multiply by 3)

Therefore, molar mass of FeCl\(_3\) = \( 55.85 + 3 \times 35.45 \)
= \( 55.85 + 106.35 \)
= \( 162.2 \, \text{g/mol} \)

2. **Calculate the Theoretical Yield:**
- From the balanced equation:
\[ 2 \, \text{Fe} \rightarrow 2 \, \text{FeCl}_3 \]
Therefore, the molar ratio of Fe to FeCl\(_3\) is 1:1.

- Moles of Fe used:
\[ \frac{32.0 \, \text{g Fe}}{55.85 \, \text{g/mol}} \approx 0.573 \, \text{mol Fe} \]

- Since the molar ratio is 1:1, the moles of FeCl\(_3\) formed will also be \( 0.573 \, \text{mol} \).

- Theoretical mass of FeCl\(_3\):
\[ 0.573 \, \text{mol} \times
