Question

Estimate the percentage of the total mass of a atom that is due to (a) electrons, (b) protons, and (c) neutrons by assuming that the mass of the atom is simply the sum of the masses of the appropriate numbers of subatomic particles. The mass of an electron is 0.00054858 amu, the mass of a proton is 1.0073 amu, and the mass of a neutron is 1.0087 amu.
