9. While hydrogen peroxide is a common compound, it readily undergoes decomposition if the chemical is left out for too long. A sample of the aqueous solution is decomposed, and the oxygen produced in the process is collected via water displacement (over water) using a gas collection tube. The data shown to the right was then recorded. 2 H₂O2 (aq) → 2 H₂O (1) + O2(g) a. What is the partial pressure of O2 (g) produced in the decomposition? b. How many of moles of O₂ (g) were produced in the decomposition? Atmospheric pressure Temperature Pvap for water at 22.8°C Volume of gas collected 758.99 torr 22.8°C 20.815 torr 193.6 mL C. Calculate the experimental mass of H₂O₂ that would need to decompose in order to form this amount of oxygen.
