### Percent Yield

**Percent Yield:**

The **theoretical yield** of an experiment is the amount of product calculated from a stoichiometry problem after identifying the limiting reactant. However, when doing an experiment there are many opportunities for error such that the **actual yield**, the amount obtained in the lab after the chemical reaction occurred, is different from the theoretical yield. The difference in the actual and theoretical yield can be written as a percent ratio, **percent yield**.

\[
\text{Percent Yield} = \left( \frac{\text{Actual Yield}}{\text{Theoretical Yield}} \right) \times 100
\]

For the following problems, identify the limiting reactant and calculate the percent yield.

1. **In an experiment, the actual yield was 3.26 grams and the theoretical yield was 3.42 grams. What was the percent yield?**

2. **A reaction between 2.1 L of Carbon dioxide and 6.7 g of Calcium hydroxide, produces Calcium Carbonate and water. However, when the experiment was done in the lab, scientists only measured a production of 9.11 grams of Calcium Carbonate.**

\[
\text{CO}_2 (\text{g}) + \text{Ca(OH)}_2 (\text{aq}) \rightarrow \text{CaCO}_3 (\text{aq}) + \text{H}_2\text{O (l)}
\]

3. **Calcium carbonate can react with sulfuric acid to produce Calcium sulfate, water, and Carbon dioxide. 54.1 g CaCO3 and 42.4 g H2SO4 react together and produce 59.2 g Calcium Sulfate.**

\[
\text{CaCO}_3 (\text{s}) + \text{H}_2\text{SO}_4 (\text{aq}) \rightarrow \text{CaSO}_4 (\text{aq}) + \text{H}_2\text{O (l)} + \text{CO}_2 (\text{g})
\]

4. **Carbon dioxide reacts with sodium hydroxide to form sodium carbonate and water. When 2.41 L of Carbon dioxide gas and 3.50 grams of Sodium hydroxide are reacted together in a lab, 4.75 grams of Sodium carbonate is produced.**

\[
