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.
To calculate the mass of a single atom, first look up the atomic mass of carbon from the Periodic Table. This number, 12.01, is the mass in grams of one mole of carbon. One mole of carbon is 6.022 x 10 23 atoms of carbon (Avogadro's number).
