What is the binding energy of 1 mole of 239/94 Pu if the mass defect is 0.001896 kg/mol
2 answers
E = mc^2 = 0.001896 kg/mol*(3E8 m/s)^2 = 1.7064E14 J/mol
Notice that I used 3E8 m/s for c but mass has more significant figurs to it. For c 3E8 is in round numbers. You may want to look up the speed of light. I think it is 2.9979E8 m/s. That will changae the final answer slightly.
