Answer:
Mass = 70.4 g
Explanation:
Given data:
Mass of CO₂ produced = ?
Mass of C₄H₁₀ = 23 g
Solution:
Chemical equation:
2C₄H₁₀ + 13O₂ → 8CO₂ + 10H₂O
Number of moles of C₄H₁₀:
Number of moles = mass/ molar mass
Number of moles = 23 g/ 58.12 g/mol
Number of moles = 0.4 mol
Now we will compare the moles of C₄H₁₀ and CO₂ from balance chemical equation.
C₄H₁₀ : CO₂
2 : 8
0.4 : 8/2×0.4 = 1.6 mol
Mass of CO₂:
Mass = number of moles × molar mass
Mass = 1.6 mol × 44 g/mol
Mass = 70.4 g
