Carbon dioxide gas is produced in the reaction $2$HN$*$O$\_\{3\}($aq$)+$ N$\_\{3\},$ C$*$O$\_\{3\}($aq$)->2$NaN$*$O$\_\{3\}($aq$)+$ C$*$O$\_\{3\}($g$)+$ H$\_\{2\}*$O$($D$)$ student added $0\mathrm{.}300$ g of sodium carbonate $($N$*$a$\_\{2\}*$C$*$O$\_\{3\})$ to $33\mathrm{.}00$ of $3\mathrm{.}0$ M nitric acid $($HN$*$O$\_\{3\})$ in a closed $250$ Erlenmeyer flask. Bubbles appeared in the solution, and the pressure increased. The temperature increased, then slowly decreased. the temperature reached $21\mathrm{.}5$ deg $*$ C the student attached a syringe to the flask. The plunger on the syringe moved until the pressure equalized. The final volume of the syringe was $68\mathrm{.}4$ Calculate the moles of carbon dioxide gas generated by the reaction
