Answer

2.4808 moles

Explanation

To solve this problem, we will use the stoichiometry of the balanced chemical equation. The equation tells us the ratio of moles of potassium permanganate ( ) to moles of carbon dioxide ( ) produced in the reaction. According to the equation, 5 moles of are produced for every 14 moles of consumed. We can set up a proportion to find the moles of consumed based on the moles of produced: Given that we have 0.886 moles of , we can solve for the moles of consumed: Now, let's calculate the moles of : So, 2.4808 moles of are consumed to form 0.886 moles of carbon dioxide.
