When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.
One mole of 12C has a mass of 12.00000 grams (exactly, by definition).One mole of 13C has a mass of 13.00335 grams.One mole of 14C has a mass of 14.00324 grams.One mole of natural carbon - i.e. a sample with the ration of isotopes equal to that in nature - has a mass of 12.0107 grams.

The reaction is: C + O2 = CO2 The volume (or the mass) of the released carbon dioxide depends on the concentration of carbon in charcoal; this is very variable.
Carbon Dioxide: CO2 C = 14.01 O = 16.00 C + 2*O= 14.01 + 2*16.00 =44.01 g/mol
Calculate (to the nearest 0.1 u) carbon dioxide, CO2
Carbon is a chemical element, and it has C as its chemical symbol. It does not have a chemical formula because it is (as stated) a chemical element, and not a chemical compound.
how much of co2 is released in by fossil fuels
Important is the percentage of calcium carbonate (CaCO3) in the material. For an equivalent mass of pure chalk or pure marble the quantity of released carbon dioxide is the same - the chemical formula is the same.
carbon dioxide contains about 27.27% carbon.
In terms of proportion of molecules that are carbon, 33% (formula: CO2 which means that there are 2 oxygens and 1 carbon). If you mean in terms of mass, then carbon is 27.27% of the molecule (Two oxygens at a molecular mass of 16 each, and one carbon at a molecular mass of 12) by mass.
The equation given shows that each formula mass of calcium carbonate produces one formula mass of CO2. The gram formula masses of calcium carbonate and carbon dioxide are 100.09 and 44.01 respectively. Therefore, to produce 4.4 grams of carbon dioxide, 4.4(100.09/44.01), or 10 grams of calcium carbonate, to the justified number of significant digits, are needed.
When methane burns, the carbon dioxide and water formed, equal the mass of the methane plus the mass of the oxygen.

First of all, carbon dioxide is a molecule and hence the question should be: What is the molecular mass of carbon dioxide? and the answer is 12 + (2 x 16) = 48

The molar mass of sodium acetate is 82,03. The molar mass of carbon dioxide is 44,01.
