Answer is: 8,45 grams of carbon (IV) oxide.

Chemical reaction:C₄H₁₀ + 13/2O₂ → 4CO₂ + 5H₂O.

m (C₄H₁₀) = 10 g.

m (O₂) = 10 g.

m (CO₂) = ?

n (C₄H₁₀) = 10 g : 58 g/mol.

n (C₄H₁₀) = 0,172 mol.

n (O₂) = 10 g : 32 g/mol.

n (O₂) = 0,3125 mol.

n (O₂) : n (CO₂) = 6,5 : 4.

n (CO₂) = 0,192 mol.

m (CO₂) = 0,192 mol · 44 g/mol.

m (CO₂) = 8,45 g.
