Chapter 3, Problem 3.61E

The chemical formula for gasoline can be approximated as ${\text{C}}_{\text{8}}{\text{H}}_{\text{18}}$. The chemical reaction for the combustion of gasoline is

$2{\text{C}}_{\text{8}}{\text{H}}_{\text{18}}\left(l\right)+25{\text{O}}_{\text{2}}\left(\text{g}\right)\to 16{\text{CO}}_{\text{2}}\left(\text{g}\right)+18{\text{H}}_{\text{2}}\text{O}\left(l\right)$

If $S\left({\text{C}}_{\text{8}}{\text{H}}_{\text{18}}\right)=361.2\text{J}/\text{mol}\cdot \text{K}$, calculate the entropy change that accompanies the combustion of $2653\text{g}\left(=\text{1}\text{.00}\text{gal}\right)$ of gasoline.
