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 defined to be exactly 12 atomic mass units) and a natural abundance of 0.9893. So nearly 99% of all carbon is carbon 12. But there are two heavier isotopes too, carbon 13 and carbon 14.
Carbon 13 has an atomic mass of 13.00335 and a natural abundance of 0.0107 (about 1.1%).
Carbon 14 has an atomic mass of 14.003 and an abundance of 0.000000000001 (1 part in a trillion). Because it is so rare, carbon 14 makes an infinitesimal contribution to the average atomic mass.
To calculate the weighted average, sum the products of the abundance X atomic mass for each isotope:
(0.9893)*(12) + (0.0107)*(13.00335) + (0.000000000001) * (14.003) =12.01074.
Round 12.01074 to 12.011, which is the accepted value.
In other units, the atomic mass of carbon is :
1. 12.0107 daltons
2. 0.0120107 kilodaltons
3. 1.99442 x 10-23 grams
4. 1.99442 x 10-26 kilograms
5. 11.1879 GeVc-2
