Given uranium
238U
92 isotope = (n*mp +n*mn+nme)
= (92*mp+146*mn+92*me)
mp= 1.007280 u
mn= 1.00867 u
me= 0.00055 u
1 atomic mass unit = 1.6660539*10^-27 kg
mass of nucleons = (92*1.00728+ 146*1.00867+92*0.00055)
= 239.9861 u
Real mass of uranium 238 is = 238.05082
mass defect is 239.9861 u- 238.05082 u = 1.93536 u
a) Binding energy = mass defect * 931.5 Mev (energy equivalent of 1 amu = 931.5 Mev )
= 1.93536 *931.5 Mev
= 1802.71 Mev
b) Binding energy per nucleon is 1802.71/ 238 = 7.57473 Mev
