(a) What is a.m.u? Express 1 a.m.u. in MeV.

(b) Write the approximate mass of a proton, neutron and electron in a.m.u.

Solution:

(a) a.m.u. stands for atomic mass unit. It is used to express the mass of atomic particles

1 a.m.u. = 931 MeV.

The mass of a proton is 1.00727 a.m.u.

The mass neutron is 1.00865 a.m.u.

The mass of electron is 0.00055 a.m.u.
