Chem 2/5 Post-lab FS/96 Exp. 302 Molar Volume of Oxygen The decomposition of sodium chlorate can be used as an emergency source of oxygen. The decomposition occurs according to the reaction in the presence of heat and a catalyst: 2 NaClO3 2 NaCl + 3 O2 If the temperature is 31.0 C and the atmospheric pressure is 0.957 atm, and a person consumes 450. liters of oxygen per day, how many grams of sodium chlorate are required to provide a four hour emergency oxygen supply for 50 people?
