Yes, every substance in the universe has mass.
Carbon dioxide.
Carbon Dioxide
Yes. CO2 has a weight of 44g/mol and O2 has a weight of 32g/mol.
Atomic weight of carbon: 12,011 Atomic weight of oxygen: 15,999 Molar mass of carbon dioxide: 12,011 + 2 x 15,999 = 44,009
Carbon dioxide (CO2). It is mainly produced by the decomposition of pressurized carbonic acid (H2CO3) into water and carbon dioxide.

The molar mass of carbon dioxide is 44,01. For global warming see the link below.
Because it has decomposed to carbon dioxide and calcium oxide, and the carbon dioxide is gaseous, has dispersed into the natural atmosphere, and therefore is no longer part of the weight.

Burning one kilo of carbon releases about 3.6 kilos of carbon dioxide. Carbon has an atomic weight of 12. Oxygen has an atomic weight of 16. The oxidation of carbon results in carbon dioxide, atomic weight 44. So 44/12 is 3.667. There are other things in coal besides pure carbon, slight impurities, so in general 1 kg of coal releases about 3.6 kg of CO2.
Carbon dioxide.
Burning one pound of carbon releases about 3.6 pounds of carbon dioxide (the extra weight comes from oxygen from the air).
Carbon dioxide.
12 (one carbon) + 2*16 (two oxygens) = 48g/mol
carbon dioxide
44.010 g/mol You can sum up atomic weight of 1 carbon and 2 oxygen to this figure.
