Question

How many grams of carbon dioxide are produced by complete combustion of 5 grams of c5h10

Answer 1

15.4 g

Step-by-step explanation:

The reaction that takes place is:

• 2C₅H₁₀ + 15O₂ → 10CO₂ + 10H₂O

First we convert 5 grams of C₅H₁₀ into moles, using its molar mass:

• 5 g ÷ 70 g/mol = 0.07 mol C₅H₁₀

Then we convert C₅H₁₀ moles into CO₂ moles, using the stoichiometric coefficients of the reaction:

• 0.07 mol C₅H₁₀ *
  `(10molCO_2)/(2molC_5H_(10))` = 0.35 mol CO₂

Finally we convert 0.35 moles of CO₂ into grams:

• 0.35 mol CO₂ * 44 g/mol = 15.4 g
