What is the empirical formula of copper chloride for this lab?

### Experiment Data and Calculation for Copper Chloride Reaction **Data:** - **Mass of copper chloride in 25.0 mL of solution:** 2.021 g **Initial and Final Mass of Zinc (Zn):** - **Initial mass of Zn:** 1.636 g - **Mass of Zn after reaction:** 0.685 g - **Mass of Zn reacted:** 0.951 g (calculated) **Additional Information:** - **Mass of filter paper:** 0.298 g - **Mass of wax paper + Cu:** - Glass dish: 50.572 g - Mass after 5 min. on Büchner funnel: 0.816 g - Mass after an additional 5 min. on bench: 0.814 g - Mass after another 5 min. on bench: 0.804 g **Calculation:** - **Mass of Cu produced:** *To be calculated* - **Mass of Cl in copper chloride:** *To be calculated* - **Moles of Cu in copper chloride:** *To be calculated* - **Moles of Cl in copper chloride:** *To be calculated* **Empirical Formula Determination:** - **Empirical formula of copper chloride:** *To be determined* ### Explanation for Diagrams and Graphs: This section of the document does not contain any diagrams or graphs. However, the data here would normally be used to determine the mass, moles, and empirical formula of copper chloride by calculating from the mass of materials before and after the reaction and using concepts of stoichiometry. The repeated measurements of copper mass over time suggest gravimetric analysis to ensure complete reaction. This educational content provides a practical insight into chemical reactions and empirical formula calculations, essential in understanding stoichiometry in chemistry.
