A mass of solid potassium chlorate undergoes thermal decomposition in the presence of a catalyst (manganese dioxide) to produce solid potassium chloride and oxygen gas. As a result, 250 mL of oxygen are collected over water at 26.0C and a total pressure of 760.0 Torr. What is the mass of potassium chlorate that decomposed?
