Compute the mass percent of naclo3 in the original sample

Reference no: EM13679682

At elevated temperatures sodium chlorate decomposes to produce sodium chloride and oxygen gas. A 0.8347-g sample of impure sodium chlorate was heated until the production of oxygen gas ceased. The oxygen gas collected over water occupied 52.4mL at a temperature of 30.Â°C as well as a pressure of 736 torr. Compute the mass percent of NaClO3 in the original sample. At 30.Â°C the vapor pressure of water is 31.8 torr.
