2b. 12 grams of C8H18 react with oxygen to produce carbon dioxide and water. How many grams of CO2 are produced?
likoan [24]

Answer:

37.1g are produced

Explanation:

The combustion of C₈H₁₈ is:

C₈H₁₈ + 25/2O₂ → 8CO₂ + 9H₂O

<em>Where 1 mole of C₈H₁₈ produce 8 moles of CO₂</em>

<em />

To find the mass of CO₂ that is produced we need to convert the mass of C₈H₁₈ with molar mass. Then, with the chemical equation, we can find the moles of CO₂ and its mass, as follows:

<em>Moles C₈H₁₈ -Molar mass: 114.2g/mol-</em>

12g C₈H₁₈ * (1mol / 114.2g) = 0.105 moles of C₈H₁₈

<em>Moles CO₂:</em>

As 1 mole of C₈H₁₈ produce 8 moles of CO₂, 0.105 moles of C₈H₁₈ produce:

0.105 moles of C₈H₁₈ * (8moles CO₂ / 1mole C₈H₁₈) = 0.84 moles of CO₂

<em>Mass CO₂ -Molar mass: 44.01g/mol-:</em>

0.84 moles of CO₂ * (44.01g / mol) = 37.0g of CO₂ ≈

<h3>37.1g are produced</h3>
