(Not guaranteed correct answer)
Balanced equation for complete combustion of methane would be:
CH4 + 2O2 --> CO2 + 2H20
Amount of CO2:
22g / [12.0+2(16.0)]
= 0.5mol
Mole ratio can be represented as
CH4 = CO2
So 0.5 mol of CO2 = 0.5 mol of CH4 ??

Answer:
2.11 x 10²⁴ molecules.
Explanation:
- <em>It is known that every 1.0 mole of a molecule contains Avogadro's number of molecules (NA = 6.022 x 10²³).</em>
<em><u>Using cross multiplication:</u></em>
1.0 mole of H₂O contains → 6.022 x 10²³ molecules.
3.5 mole of H₂O contains → ??? molecules.
∴ 3.5 mole of H₂O contain = (3.5 mol)(6.022 x 10²³) = 2.11 x 10²⁴ molecules.
