Determine the mass in grams of ${\mathrm{CO}}_2$ that are produced by the complete reaction of 10.49 grams of ${\mathrm{C}}_6{\mathrm{H}}_{12}$ (cyclohexane) according to the following combustion reaction: ${\mathrm{C}}_6{\mathrm{H}}_{12}(\mathrm{l})+9{\mathrm{O}}_2(\mathrm{g})?6{\mathrm{CO}}_2(\mathrm{g})+6{\mathrm{H}}_2\mathrm{O}(\mathrm{g})$ What mass in grams of ${\mathrm{NaN}}_3$ is required to produce $50.2\mathrm{L}$ of ${\mathrm{N}}_2$ gas (density $=1.25\mathrm{g}/\mathrm{L}$ ) according to the balanced chemical reaction: 2 ${\mathrm{NaN}}_3(\mathrm{s})?2\mathrm{Na}(\mathrm{s})+3{\mathrm{N}}_2(\mathrm{g})$
