The term 'mass defect' describes the fact that the mass of the product of a nuclear reaction (such as a helium-4 nucleus from hydrogen atoms) is less than the mass of the individual four nucleons. true false the actual measured mass of a beryllium-9 atom is 9.012182 atomic mass units (amu) and the expected mass is calculated to be 9.072429 amu. therefore, the mass defect for a beryllium-9 nucleus is 0.0624 amu. (1 amu= 1.66x10-27 kg) how much energy will this reaction provide? 3.12 x 10-20 kg m2/s2 9.36 x 10-12 kg m2/s2 3.46 x 10-36 kg m2/s2 1.11 x 10-11 kg m2/s2 in a nuclear reaction, the energy released is 3.0 x 1020 joules. to what mass does this amount of energy equate? (1 j = 1 kg m2/s2) 2.7 x 1036 kg 1.0 x 1012 kg 3.3 x 103 kg 2.7 x 10-4 kg if 3.0 kilograms of gasoline were burned in a car engine, they would yield 140,000,000 joules, which is a tremendous amount of energy. however, burning the gasoline only produces a chemical change. convert those 3.0 kilograms of gasoline completely into energy, using einstein's equation. (1 j = 1 kg m2/s2) 2.7 x 1017 kg m2/s2 2.7 x 1015 kg m2/s2 9.0 x 108 kg m2/s2 3.3 x 10-16 kg m2/s2 what is the average binding energy per nucleon for a u-238 nucleus with a mass defect of 0.184 amu? (1 amu= 1.66 x 10-27 kg; 1 j = 1 kg m2/s2) 2.38 x 10-30 j 2.75 x 10-11 j 1.01 x 10-20 j 1.16 x 10-13 j
