Diesel fuel for automobiles and trucks is a mixture of hydrocarbons that can be modeled by C ₁₆H₃₄.How many grams of O₂ are needed to react with 0.500 mol C₁₆H₃₄?

Question

Quizplus · Accepted Answer

The balanced equation for the combustion of C16H34 is: 2 C16H34 + 49 O2 → 32 CO2 + 34 H2O. Therefore, 0.500 mol of C16H34 requires 12.25 mol of O2. The molar mass of O2 is 32 g/mol, so 12.25 mol of O2 weighs 392 g.
