Answer:
9.03*10^23 molecules CH4
Explanation:
In the equation CH4 + O2 -> CO2 + 2H2O, the molar ratio of CH4 to CO2 is 1:1. It takes 1 mole of CH4 burned to form 1 mole of CO2. If we convert molecules to moles, we do 9.03 x 10^23 divided by 6.02 x 10^23 = 1.5 moles of CO2. Since we know the ratio is 1:1, that meant it would take 1.5 moles of CH4 burned to make that much CO2. So we convert our 1.5 moles of CH4 into molecules by multiplying 1.5 * 6.02 x 10^23 which equals 9.03*10^23 molecules CH4.
