...carbon-12 open cap c 612 close isotope. How many protons and neutrons does cap c 612 contain? Answer Six protons and six neutrons. Atomic mass is expressed in terms of so-called atomic mass units (amu). Where 1 amu = 1.661 x 10-24 g This number is equal to one twelfth of the mass of an atom of carbon-12. Every element is assigned an atomic mass, which is its mass relative...
