$\displaystyle \mathrm{NaClO}_3$ is used, even in spacecrafts, to produce $\displaystyle \mathrm{O}_2$. The daily consumption of pure $\displaystyle \mathrm{O}_2$ by a person is $\displaystyle 492$ L at $\displaystyle 1 \mathrm{~atm}, 300 \mathrm{~K}$. How much amount of $\displaystyle \mathrm{NaClO}_3$, in grams, is required to produce $\displaystyle \mathrm{O}_2$ for the daily consumption of a person at $\displaystyle 1$ atm, $\displaystyle 300$ K? \_\_\_\_. $$\begin{aligned} & \mathrm{NaClO}_3(\mathrm{~s})+\mathrm{Fe}(\mathrm{~s}) \rightarrow \mathrm{O}_2(\mathrm{~g})+\mathrm{NaCl}(\mathrm{~s})+\mathrm{FeO}(\mathrm{~s}) \\ & \quad \mathrm{R}=0.082 \mathrm{~L} \mathrm{~atm} \mathrm{~mol}^{-1} \mathrm{~K}^{-1} \end{aligned} $$
