Calculate the nuclear binding energy (in joules) and the nuclear
binding energy per nucleon of:
113 | Cd | |
48 | |
(112.904401 amu)
(Round each final answer to 4 significant figures.)
______J
_______J/nucleon
No. of protons in cadmium = 48
No. of neutrons in cadmium = 113-48 = 65
Theoretical mass of cadmium = 48(1.007825 amu) + 65(1.008665 amu) = 48.3756+65.5632 = 113.9388 amu
Actual mass of cadmium = 112.904401 amu
Mass defect = actual mass - theoretical mass of cadmium = 112.904401 - 113.9388 = -1.034399 amu
1 amu ---> 1.49 x 10-10 J
-1.034399 amu -----> === Nuclear Binding energy in Joules = -1.03499 amu x 1.49 x 10-10 J/1 amu = - 1.542 x 10-10 J (with four significant numbers)
Nuclear Binding energy/nucleon = Binding energy/nucleon = - 1.542 x 10-10 J/113 nucleons = -0.01365 x 10-10 J/nucleon = -1.365 x 10-12 J/nucleon (with four significant numbers)
