307.94g of CO₂

Explanation:

Equation of reaction

2C₈H₁₈ + 25O₂ → 16CO₂ + 18H₂O

molarmass of C₈H₁₈ = 114.33g/mol

2 moles of C₈H₁₈ = 228.66g/mol

Molar mass of CO₂ = 44.0095g/mol

16 moles of CO₂ = 704.152g/mol

From equation of reaction,

2 moles of C₈H₁₈ reacts with 16 moles of CO₂;

228.66g of C₈H₁₈ = 704.152g of CO₂

100g of C₈H₁₈ = y moles of CO₂

y = (100 * 704.152) / 228.66

y = 307.94g of CO₂

Therefore, 100g of C₈H₁₈would yield 307.94g of CO₂.

no but i do not usually comment or use my voice that much when it comes to social media

im not exactly sure but i think its b!
