F) Calculate the binding energy per nucleon of the helium nucleus 32He. Express your answer in millions of electron volts to four significant figures.

Explanation / Answer

b)

number of proton = 8

number of neutron = 8

total mass of proton = 1.007276*8 = 8.058208 u

total mass of neutron = 1.008664*8 = 8.069312 u

mass of O = 15.9994 u

mass defect = 8.058208 + 8.069312 - 15.9994 =0.12812 u

1 u corresponds = 9.31494*10^8 ev

binding energy = energy of 0.12812 u

= 0.12812 u * 9.31494*10^8 ev

= 1.1934*10^8 eV

= 119.3 million eV

C)

number of nucleon = 16

binding energy per nucleon = 119.3/16 = 7.456 million eV /nucleon
