In the reaction CH₄ + 2 O₂ → CO₂ + 2 H₂O, how many moles of oxygen are required to burn 16.0 g of methane?

Question

Quizplus · Accepted Answer

The balanced chemical equation is CH4 + 2 O2 → CO2 + 2 H2O. To burn 16.0 g of methane (CH4), which has a molar mass of approximately 16.0 g/mol, we have 1 mole of CH4. According to the equation, 2 moles of O2 are required for every mole of CH4, so 2 moles of O2 are needed.
