Verified step by step guidance
1
Identify the chemical formula of hydrogen peroxide, which is H₂O₂. This indicates that each molecule contains 2 oxygen atoms.
Understand that the problem asks for the number of moles of oxygen atoms, not molecules. Therefore, you need to consider the number of oxygen atoms per molecule.
Recognize that for every mole of H₂O₂, there are 2 moles of oxygen atoms because each molecule of H₂O₂ contains 2 oxygen atoms.
Set up the calculation using the relationship: \( \text{moles of oxygen atoms} = \text{moles of H₂O₂} \times 2 \).
Substitute the given value into the equation: \( \text{moles of oxygen atoms} = 4.96 \text{ mol H₂O₂} \times 2 \).
