11. At elevated temperatures, sodium chlorate decomposes to produce sodium chloride and oxygen gas. A 0.8685-g sample of impure sodium chlorate was heated until the production of oxygen gas ceased. The oxygen gas collected over water occupied 51.2 mL at a temperature of 25°C and a pressure of 731 torr. Calculate the mass percent of NaClO3 in the original sample. (At 25°C the vapor pressure of water is 23.8 torr.)
