Number of Protons =92
Number of neutrons =238-92 =146
Mass of neutron =1.008665 amu
Mass of protons =1.007825 amu
Mass of uranium =238.0507882
Mass of defect=238.0507882-92×1.007825-146×1.008665=1.9342018 amu
Binding energy per nucleon=1.9342018×931.5/238 =7.57 MeV
So, second option is correct
Thank you and please thumbs up

How does the DeBroglie wavelength of the electron in the ground state of a hydrogen atom compare to the DeBroglie wavelength of the electron when it's in a 2p state? The DeBroglie wavelengths of the two electrons are equal. The DeBroglie wavelength of the electron in the ground state is greater than that of the electron in a 2p state. The DeBroglie wavelength of the electron in the ground state is less than that of the electron in a 2p...
