At elevated temperatures, sodium chlorate decomposes to produce sodium chloride and oxygen gas. a 0.8765-g sample of impure sodium chlorate was heated until the production of oxygen gas ceased. the oxygen gas collected over water occupied 57.2 ml at a temperature of 22ºc and a pressure of 734 torr. calculate the mass percent of nahco₃ in the original sample. (at 22ºc the vapor pressure of water is 19.8 torr.)
