Calculate the binding energy per nucleon of a 24He nucleus (alpha particle) using the following data:
Proton mass mp=1.007825u, neutron mass mn=1.008665u, nuclear mass of 24HeM=4.002603u, and 1u=931.5MeV/c2. Express your answer to one decimal place in MeV per nucleon.
(a) 28.3MeV
(b) 14.1MeV
(c) 7.1MeV
(d) 6.8MeV
