At elevated temperatures, solid sodium chlorate decomposes
Chapter 6, Problem 71(choose chapter or problem)
At elevated temperatures, solid sodium chlorate decomposes to produce sodium chloride, NaCl, and O2 gas. A 0.8765 g sample of impure sodium chlorate was heated until the production of oxygen ceased. The oxygen gas was collected over water and occupied a volume of 57.2 mL at and 734 Torr. Calculate the mass percentage of in the original sample. Assume that none of the impurities produce oxygen on heating. The vapor pressure of water is 21.07 Torr at
