WebCarbon-12 has a mass of 12 amu by definition. Theoretically, this would mean that each proton and each neutron has a mass of one amu, but this turns out not to be so. The actual mass of a proton is about 1.007 amu, and the mass of a neutron is about 1.008 amu. If you add the masses of six protons and six neutrons, you get 12.09.
