NaClO 3 is used, even in spacecrafts, to produce O 2 . The daily consumption of pure O 2 by a person in 492 L at 1 atm, 300 K . How much amount of NaClO 3 , in grams, is required to produce O 2 for the daily consumption of a person at 1 atm, 300 K ? _____ NaClO 3 s + Fe s → O 2 g + NaCl s + FeO s R = 0 .082 L atm mol - 1 K - 1

Correct answer

0

Step-by-step solution

Mol of NaClO 3 = Mol of O 2 Mol of O 2 = PV RT = 1 × 492 0 .082 × 300 = 20   mol Mass of NaClO 3 = 20 × 106 .5 = 2130   g
