DedPeter [7]

The atomic mass of a carbon isotope that has 6 protons and 7 neutrons is<u> </u><u>13</u>

Explanation:

Remember that whilst the atomic number represents the number of protons in an atom, the mass number represents the summation of protons and neutrons particles in the atomic nuclei. Therefore, in this case, the carbon will have a mass number of;
