The average atomic mass of carbon made up of 2 naturally occurring isotopes, 12C and 13C are 12.01 u.

The average atomic mass of an element

The average atomic mass of carbon made up of 2 naturally occurring isotopes, 12C and 13C is 12.01 u.

The element carbon has two naturally occurring isotopes.

  • 12C with an atomic mass of 12.00 u and an abundance of 98.93%

  • 13C with an atomic mass of 13.00 u and an abundance of 1.07%.

The average atomic mass is expressed:

AAM = (12.00 * 98.93) + (13.00 * 1.07)

AAM = 12.01 amu

The average atomic mass of carbon made up of 2 naturally occurring isotopes, 12C and 13C are 12.01 u.
