A carbon-12 atom consists of six protons, six neutrons and six electrons. The unified atomic mass unit (u) is defined as 1/12 the mass of the carbon-12 atom. Calculate:
a. The mass defect in kilograms
b. The binding energy
c. The binding energy per nucleon.
(Mass of a proton = 1.007 276 u, mass of a neutron = 1.008 665 u, mass of an electron = 0.000 548 u.)
