Calculate the mass defect in Fe-56 if the mass of an Fe-56 nucleus is 55.921 u. The mass of a proton is 1.00728 u and the mass of a neutron is 1.008665 u.

Question

Quizplus · Accepted Answer

The mass defect is the difference between the mass of the nucleus and the sum of the masses of its individual protons and neutrons. For Fe-56, the mass defect is:Mass defect = (56 * 1.008665 u) + (26 * 1.00728 u) - 55.921 u = 0.528 u
