The average atomic mass of carbon is 12.011. This is a weighted average based on three forms (isotopes) of carbon with different natural abundances. Carbon 12 has an atomic mass of 12.00 (carbon 12 is a special case because its mass is <i>defined</i> to be exactly 12 atomic mass units) and a natural abundance of 0.9893.
Carbon has an atomic weight of 12, the atomic weight of oxygen is 16. Therefore, when one kg of carbon combines with oxygen we have 12 mass units of carbon and 32 units of oxygen being converted into 44 units (12 + 16 + 16 = 44) of carbon dioxide. 1kg of carbon becomes 1 x 44/12 = 3.7kg (approximately) of CO2.
