Chapter 10, Problem 57RQ

How many milliliters of ${\text{O}}_{\text{2}}$ are consumed in the complete combustion of a sample of hexane, ${\text{C}}_{\text{6}}{\text{H}}_{\text{14}}$, if the reaction produces 855 mL of ${\text{CO}}_{\text{2}}$? Assume all gas volumes are measured at the same temperature and pressure. The reaction is

$\begin{array}{l}{\text{2C}}_{\text{6}}{\text{H}}_{\text{14}}\left(g\right){\text{ + 19O}}_{\text{2}}\left(g\right)\stackrel{}{\to }{\text{12CO}}_{\text{2}}\left(g\right){\text{ + 14H}}_{\text{2}}\text{O}\left(g\right)\hfill \\ \hfill \end{array}$
