Your number for natural gas which is 97% methane is backwards the chemical formula for methane is CH4 so it’s 75% hydrogen 25% carbon by mole. The rest is ethane,nitrogen,argon,and CO2 at pipeline grade must be less than 3% of the gasses. Even ethane is C2H8 also a 2/8=1/4 ratio of carbon to hydrogen.
By weight. [rolls eyes]
Did you just finish CH101?

Weight as in mass in a gravitational field...I think you mean mass as in atomic mass and that’s irrelevant when looking at stoichiometric equations. It’s the number of mols of atoms that matters hence 4 to 1.
Burning one molecule of CH4 releases one CO2 and two H2O. That ratio is fixed regardless of the mass of the atoms themselves. Burning methane will ways produce one CO2 for every two water. On a LHV basis equalized out for equal megajoules of thermal output methane will produce much less CO2 per megajoule because its only one in four molecules of carbon to hydrogen.
