If 2 moles of C₂H₅OH completely burn to CO₂ and water, what is the mass of carbon dioxide formed?

A. 88 kg
B. 176 g
C. 44 g
D. 132 g

Answer :

Final answer:

When 2 moles of C₂H₅OH completely burn, the mass of carbon dioxide formed is approximately 88 grams.

Explanation:

To calculate the mass of carbon dioxide formed when 2 moles of C₂H₅OH completely burn, we need to use the stoichiometry of the balanced chemical equation. The balanced equation for the combustion of ethanol (C₂H₅OH) is:



C₂H₅OH + 3O₂ → 2CO₂ + 3H₂O



From the equation, we can see that for every 2 moles of C₂H₅OH, we get 2 moles of CO₂. The molar mass of CO₂ is approximately 44 grams/mole. Therefore, the mass of carbon dioxide formed would be:



2 moles * 44 grams/mole = 88 grams
