Answer:

First option is the correct choice.

Explanation:

Write down the balanced chemical equation:

[tex]C_2H_5OH+3O_2\Rightarrow \:2CO_2+3H_2O[/tex]

One mole of ethanol produces two moles of carbon dioxide.

[tex]Ethanol\:(C_2H_5OH)\quad |\quad Carbon \:Dioxide\:(CO_2)\\\\\quad 1\:\:mole\quad \quad |\quad 2\:moles[/tex]

[tex]\quad 64.2\:\:moles\quad |\quad 2 \times 64.2 \:moles\\\\\quad 64.2\:\:moles\quad |\quad 128.4\:\moles[/tex]

Best Regards!
