[RxN - Balanced] CH₄ + 2O₂ → CO₂ + 2H₂O
[Given] 2 mol CH₄
[Solve] x g O₂
<u>Step 2: Identify Conversions</u>
[RxN] 1 mol CH₄ → 2 mol O₂
[PT] Molar Mass of O - 16.00 g/mol
Molar Mass of O₂ - 2(16.00) = 32.00 g/mol

128 g O₂ ≈ 100 g O₂
Explanation:
(a) As per the mole concept, one mole of any atom contains atoms or molecules, that is, Avogadro's number of atoms.
Therefore, 1 mole of =
molecules
= molecules
1 mole of =
molecules
= molecules
1 mole of =
molecules
= molecules
Hence, there are equal number of molecules present in the given atoms.
(b) Mass of each given atom will be calculated as follows.
Mass = no. of moles × molar mass
As one molecule of contains 2 atoms of hydrogen.
So, mass of 1 mole of =
= 2.016 g
mass of 1 mole of =
= 31.996 g
mass of 1 mole of =
= 37.996 g
Thus, we can conclude that has the greatest mass.
