Question

Quizplus · Accepted Answer

The balanced chemical equation for the combustion of propanoic acid (C3H6O2) is:$$ C_3H_6O_2 + 4.5O_2 \rightarrow 3CO_2 + 3H_2O $$Thus, for every mole of propanoic acid, 4.5 moles of $O_2$ are required. For 6 moles of propanoic acid, $6 \times 4.5 = 27$ moles of $O_2$ are needed.
