Answer:
142.0 moles CO₂
Explanation:
To answer this question, we first need to know what a mole is. A mole represents of something, and in this case, that something is molecules.
So, to convert molecules into moles, we need to use the conversion factor .
Doing so (using dimensional analysis) gives us:
