The mass defect for a Li-6 nucleus is -0.03434 g/mol. How do you calculate the atomic mass of Li-6?
The total mass of protons in the nucleus
The total mass of neutrons in the nucleus
The mass defect
Total mass of the nucleons ( protons + neutrons)
Mass of the nucleus
Note that the mass defect is due to the binding energy - i.e. The energy required to keep the nucleons together in the nucleus.
