Explanation:

Hello!

In this case, when methane is burnt in the presence of carbon dioxide, the following chemical reaction is carried out:

[tex]CH_4+2O_2\rightarrow CO_2+2H_2O[/tex]

Thus, since there is a 1:2 mole ratio between methane and oxygen, we set up the following mathematical expression to obtain the produced mass of carbon dioxide as a result of the reaction:

[tex]m_{CO_2}=62.8gCH_4*\frac{1molCH_4}{16.05gCH_4}*\frac{1molCO_2}{1molCH_4} *\frac{44.01gCO_2}{1molCO_2} \\\\m_{CO_2}=172.2gCO_2[/tex]
