What is the energy released when the particles of uranium -237 are separated
Mass of uranium -237.0440u, mass of proton = 1.0073u
Mass of neutron = 1.0087u, 1u= 931Mev, 1ev = 1.6 x 10o19J
Solution
Mass defect, ∆m = mass of proton + mass of neutron – mass of uranium
= (92 x 1.0073 + 145 x 1.0087) – 237.0440
= (92.6716 + 146.2615) – 237.0440
= 238.9331 – 2370440
= 1.8891u
IU = 931mev
= 1.8891 x 931
= 1758.7521mev
Iev = 1758.7521 x 1.6 x 10-19 x 106
= 2.814 x 10-10J
