I AM BEGGING PLEASE HELP ME OUT

Answer 1

First option is the correct choice.

Step-by-step explanation:

Write down the balanced chemical equation:

`C_2H_5OH+3O_2\Rightarrow \:2CO_2+3H_2O`

One mole of ethanol produces two moles of carbon dioxide.

`Ethanol\:(C_2H_5OH)\quad |\quad Carbon \:Dioxide\:(CO_2)\\\\\quad 1\:\:mole\quad \quad |\quad 2\:moles`

`\quad 64.2\:\:moles\quad |\quad 2 * 64.2 \:moles\\\\\quad 64.2\:\:moles\quad |\quad 128.4\:\moles`
