Please help with question 2 d-f
**Experiment Description:** A student performed an experiment as described, using 5.00 mL of an aqueous 3.00% \( \text{H}_2\text{O}_2 \) solution, with a density of 1.101 g/mL. The water temperature was 24.0 °C, and the barometric pressure was 29.34 inches of Hg. The weights of the gas-collection bottle and water were: - Partially full: 248.25 g - Full: 306.03 g **Tasks:** a. **Calculate the atmospheric pressure of your environment in mmHg from a weather barometric reading.** b. **Calculate the pressure exerted by the collected \( \text{O}_2 \) at the water temperature.** \( P_{\text{total}} = P_{\text{O}_2} + P_{\text{H}_2\text{O}} \) where the vapor pressure of \( \text{H}_2\text{O} \) at 24 °C = 22.4 mmHg. c. **Convert this pressure to atmospheres OR kPa.** d. **Using the assumption that 1 gram of water is 1 mL of volume, what is the volume in Liters of \( \text{O}_2 \) that was obtained?** e. **Convert the water temperature, in Celsius, to Kelvin.**

Certainly! Here's the transcribed content suitable for an educational website: --- f. **Using the density of H₂O₂, calculate the mass of 5.00 mL of the H₂O₂ solution.** g. **Since the concentration of the H₂O₂ solution is 3% by mass, calculate the mass of H₂O₂ in the mass determined from the previous part of the 5.00 mL of the solution.** h. **Using the molar mass of H₂O₂, calculate the number of moles of H₂O₂ reacting.** i. **Using stoichiometry and the balanced chemical equation for the decomposition of H₂O₂, calculate the number of moles of collected O₂. Determine how many grams this is equivalent to.** j. **Determine the gas constant, R.** k. **Calculate the % error in R for this determination.** --- This section contains a series of chemistry exercises related to hydrogen peroxide (H₂O₂). Students are expected to perform calculations involving density, concentration, molar mass, stoichiometry, and error analysis.
