You are given 2.773 g of a mixture of KClO3 and KCl. When heated, the KClO3 decomposes to KCl and O2, 2 KClO3 (s) → 2 KCl (s) + 3 O2 (g), and 803 mL of O2 is collected over water at 22 °C. The total pressure of the gases in the collection flask is 751 torr. What is the weight percentage of KClO3 in the sample? The formula weight of KClO3 is 122.55 g/mol. The vapor pressure of water at 22 °C is 19.8 torr.
