The general formula for calculation is:
Atomic weight = (Atomic Mass of the isotope a X fraction of the isotope a) + (atomic mass of the isotope b X fraction of the isotope b) + .......(atomic mass of the isotope n X fraction of the isotope n)
Don't confuse atomic weight with atomic mass, mass number or atomic number.
For carbon:
Atomic weight = (12 x 0,9893) + (13,0033548378 x 0,0107) = 12,0107
After IUPAC tables from 2009 the atomic weight of carbon is writed as
[12,0096; 12,0116].

What is the mass of one carbon atom?
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.
What is relationship between atomic mass and average atomic mass?
The average atomic mass is the ratio of the average mass of one atom of an element to one twelfth of the mass of an atom of carbon-12. It is, the mass of an atom of the substance, rescaled so that carbon-12 would have a mass of 12.
How do you calculate the average atomic mass of a element?
The mass of the isotope multiplied by its relative abundance plus the the mass times abundance of other isotopes.(mass of isotope)(relative abundance) + (mass of isotope)(relative abundance) = average atomic massExample: Carbon can be naturally found as carbon- 12 or carbon- 13. The mass of carbon- 12 is 12 amu and it makes up 98.93% of naturally found carbon. The mass of carbon- 13 is 13.00335 amu, and it makes up 1.07% of naturally found carbon. So the equation to calculate the average atomic mass of carbon is:(0.9893)(12 amu) + (0.0107)(13.00335 amu) = 12.01 amu
What is the atomic mass of carbon?
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 daltons2. 0.0120107 kilodaltons3. 1.99442 x 10-23 grams4. 1.99442 x 10-26 kilograms5. 11.1879 GeVc-2
Atomic mass number of carbon?
The Atomic number of Carbon is 6. The Atomic mass of Carbon depends on the isotope and may be from 8 to 22. Carbon 12 and Carbon 13 are the only stable isotopes of Carbon. Carbon 14 is the longest-lived unstable (radioactive) isotope. Only Carbon 12, 13 and 14 are found in nature.
Atomic mass and number for carbon?

Which element has an atomic number of 6?
Carbon is a none metal element. atomic number of it is 6.
How do you compute the neutrons of carbon?
Roughly, subtract the atomic number (6) from it's atomic mass (12.01) and round to the nearest integer to get the average number of neutrons in a carbon sample, in this case 6.
What is the average number of neutrons in carbon?
6 neutrons. you take the mass, and subtract the atomic number.
