What was the partial pressure of oxygen

Reference no: EM13169439

A student heats a sample of KClO3, KCl and MnO2 having a mass of 3.6349 g. After the reaction is complete, she has collected 346.2 mL of oxygen in a water-filled flask. The room temperature and pressure were 23.6 deg C and 763.4 mm Hg respectively. The residue had a mass of 3.1915 grams. What was the partial pressure of oxygen?
