# Data Sheet ## II. Determining the Volume of O₂ Produced from the H₂O₂ Solution ### Experiment Details: - **Code number of H₂O₂ solution:** - **Density of H₂O₂ solution:** 1.02 g/mL - **Mass percent H₂O₂ in H₂O₂ solution:** 2.7% ### Determinations: | | Determination 1 | Determination 2 | Determination 3 | |-------------|-----------------|-----------------|-----------------| | **Volume of H₂O₂ solution used, mL** | 5 | 5 | 5 | | **Water temperature, °C** | 19 | 19 | 19 | | **Barometric pressure, in. Hg** | 29.6 | 29.6 | 29.6 | | **Barometric pressure, torr** | 751.84 | 751.84 | 751.84 | | **Pressure of collected O₂ at water temperature, torr** | 735.34 | 735.34 | 735.34 | | **Water temperature, K** | | | | | **Second buret reading, mL** | 47.4 | 47.1 | 46.9 | | **First buret reading, mL** | 0.2 | 0.3 | 0.1 | | **Volume of O₂ collected at laboratory T and P, mL** | | | | ### Additional Information: - **P(H₂O vap) = 16.5 torr** This data sheet shows measurements for an experiment that determines the volume of oxygen gas produced from hydrogen peroxide (H₂O₂) solution. Three determinations provide consistent data on volumes, pressures, and temperatures, crucial for calculating the amount of oxygen generated under specific conditions.

**Title: Prop0377: Determining the Molar Volume of Oxygen** This educational resource provides a structured approach to determine the molar volume of oxygen. The following table serves as a guideline for recording measurements throughout the experiment. **Table of Measurements:** 1. **Volume of Collected O₂ at STP, mL** - Measurement for Trial 1: [3a] - Measurement for Trial 2: [3b] - Measurement for Trial 3: [3c] 2. **Mass of the H₂O₂ Solution, g** - Value for Trial 1: [4a] - Value for Trial 2: [4b] - Value for Trial 3: [4c] 3. **Mass of H₂O₂ in the Solution, g** - Measure for Trial 1: [5a] - Measure for Trial 2: [5b] - Measure for Trial 3: [5c] 4. **Number of Moles of H₂O₂ Reacting** - Data for Trial 1: [6a] - Data for Trial 2: [6b] - Data for Trial 3: [6c] 5. **Number of Moles of O₂ Collected** - Information for Trial 1: [7a] - Information for Trial 2: [7b] - Information for Trial 3: [7c] 6. **Molar Volume of O₂ at STP, L mol⁻¹** - Results for Trial 1: [8a] - Results for Trial 2: [8b] - Results for Trial 3: [8c] 7. **Mean Molar Volume of O₂ at STP, L mol⁻¹** - Overall Mean: [9] 8. **Percent Error, %** - Calculation: [value] Each column represents a different trial, ensuring data consistency and reliability. The experiment's goal is to calculate the mean molar volume of oxygen and evaluate its accuracy by determining the percent error in comparison to the accepted standard. This structured format aids in a thorough analysis and understanding of the experimental process.
