NEET Chemistry Mole Concept MCQ Question
In the balanced chemical equation for the combustion of propane, C3H8, how many moles of oxygen gas (O2) are required to completely react with 2 moles of propane?
5 moles
10 moles
6 moles
8 moles
Correct Answer
Detailed Explanation
The balanced equation for the combustion of propane is C3H8 + 5O2 → 3CO2 + 4H2O. Thus, 5 moles of O2 are needed for each mole of C3H8, resulting in 10 moles of O2 for 2 moles of C3H8.
