Based on the chemical equation 2 moles of oygen gas produces 1 mole of carbon dioxide, using this relationship we can set up an equation that would determine the amount of moles needed to produce 5.67 moles of carbon dioxide:
[tex]\begin{gathered} 5.67molCO_2\times\frac{2\text{ }molO_2}{1\text{ }molCO_2}=11.34\text{ }mol\text{ }O_2 \\ \end{gathered}[/tex]Answer: It will require 11.34 mol O2 gas.
