$\text{NaCl}{\text{O}}_3$ is used in spacecraft to produce ${\mathrm{O}}_2$. The daily consumption of pure ${\mathrm{O}}_2$ by a person is $\text{492}\text{L}$ at $\text{1}\text{atm,}$ $\text{300}\text{K}\text{.}$ How much amount of $\text{NaCl}{\text{O}}_3$ (in grams) is required to produce ${\mathrm{O}}_2$ for the daily consumption of a person at $\text{1}\text{atm,}$ $\text{300}\text{K?}$

$\text{NaCl}{\text{O}}_3\left(\mathrm{s}\right)+\text{Fe}\left(\mathrm{s}\right)\to {\mathrm{O}}_2\left(\mathrm{g}\right)+\text{NaCl}\left(\mathrm{s}\right)+\text{FeO}\left(\mathrm{s}\right)\mathrm{ }\mathrm{ }\mathrm{R}=0.0\text{82 L atm mo}{\text{l}}^{–1}{\mathrm{K}}^{–1}$
