NaClO_{3} is used, even in spacecrafts, to produce O_{2} . The daily consumption of pure O_{2} by a person is 492L 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)\rightarrow O_{2}(g)+NaCl(s)+FeO(s) R=0.082\; L\; atm\; mol^{-1}K^{-1}

best_answer

moles of NaClO_{3} = moles of O_{2}

\mathrm{moles\: of\: O_{2}\: =\: \frac{PV}{RT}\: =\: \frac{1\, x\, 492}{0.082\, x\, 300}\: =\: 20ml}

Mass of NaClO_{3}=20\times 106.5=2130g
