In a fission process, the decrease in mass is 0.01%. How much energy could be obtained from the fission of 0.1g of the material
9.0×109J
9.0×1010J
6.3×1011J
9.0×1011J
Correct answer is A
In general, the energy released during nuclear fission is given by the Einstein's mass-energy equation, given by
E=ΔMC2
Where Δm is the mass defect, and C is the speed of light.
Therefore
Δm=0.01×1.0g=1.0×10−4=1.0×10−7kgEnergy Released =ΔMC2=1.0×10−7×(3.0×108)2=1.0×10−2×9.0×1016=9.0×109J
