9. Small quantities of oxygen gas can be prepared in the laboratory by the following reaction: 2 KCIO3 (s) → 2 KCI (aq) + 3 02 (g) In such an experiment, 422 mL of oxygen gas were collected over water. The gas mixture includes oxygen and water vapor. The temperature of this gas mixture was 23.0 °C and the total pressure was 757 mm Hg. How many moles of oxygen did you prepare? The vapor pressure of water at 23.0°C is 21.1 mm Hg. 10. Nitroglycerin is a powerful explosive. Its decomposition is represented by the following reaction: 4 C3H5N3O9 (→→ 6 N2(g) + 12 CO2(g) + 10 H₂O (1) + O2(g) If 92.6 g of nitroglycerin reacts and 17.2 L of N₂ gas are collected at 412 K and 0.979 atm, what is the percent yield of the reaction?
