Chapter 4, Problem 4.11YT

Using Chemical Equation Coefficients as Conversion Factors (Mass to Mass)

One of the reactions occurring in automobile engines is the combustion of octane $\left({\text{C}}_{\text{8}}{\text{H}}_{\text{18}}\right)$:

${\text{2 C}}_{\text{8}}{\text{H}}_{\text{18}}{\text{+ 25 O}}_{\text{2}}\to {\text{ 16 CO}}_{\text{2}}{\text{+ 18 H}}_{\text{2}}\text{O}$

Assume that gasoline is pure octane and that you burn approximately $\text{6}\text{.44 }\times {\text{ 10}}^{\text{4}}$ grams of octane per week (about 20 gal). How many grams of ${\text{CO}}_{\text{2}}$ are produced?
