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
As diamonds are almost pure carbon, the atomic mass would be carbon's atomic mass: 12.0107
Carbon-12 is the most common form of Carbon and therefore, counts for most of the atomic mass.
Carbon is a non metal element. Atomic mass of it is 12.
the atomic mass carbon is 12.011 g/mol 12.011/mol = the mass of one atom 12.011/6.022x10 raised to the power of 23 this equals 1.994520093 x 10 raised to the power of -23 this is the mass of one atom of carbon in grams.
No. A carbon atom has both an atomic number and an atomic mass. All carbon atoms have an atomic number of 6. The most common carbon atom has an atomic mass of 12. See the Related Questions for more information about carbon, isotopes and atomic number and atomic mass.Go to Answers.com and punch in "carbon isotopes" and it will show you various isotopes and the atomic mass (u) associated with each (shown as isotopic mass).
