We’re being asked to estimate the amount of energy released upon the fission of 5 kg of Pu-239.
We can calculate the energy using the following steps:
Step 1: Calculate the mass of fissionable material in kg.
Step 2: Calculate the energy using the following equation:
E = energy, in J ( J = kg•m2/s2)
m = mass, in kg
c = speed of light, 3.00x108 m/s
Given that 0.1 percent of the mass of a sample of fissionable material is converted to energy upon nuclear fission. Estimate the amount of energy released upon the fission of 5 kg of Pu-239.
A. 4.5 × 1011 kJ
B. 4.5 × 1014 kJ
C. 1.5 × 104 kJ
D. 1.5 × 107 kJ
