Determine the binding energy of a F-19 nucleus.The F-19 nucleus has a mass of 18.99840325 amu.A proton has a mass of 1.00728 amu,a neutron has a mass of 1.008665 amu,and 1 amu is equivalent to 931 MeV of energy.

Question

The total mass of 9 protons and 10 neutrons is:
(9 protons * 1.00728 amu/proton) + (10 neutrons * 1.008665 amu/neutron) = 18.99840325 amu (the mass of F-19 nucleus)

The binding energy can be calculated as:
mass defect * c^2 = (mass of individual nucleons - mass of nucleus) * c^2
mass defect = (9 * 1.00728 amu + 10 * 1.008665 amu - 18.99840325 amu) = 0.09788375 amu

Binding energy = mass defect * 931 MeV/amu = 91.13 MeV = 143 MeV (rounded to the nearest MeV)
