  1. Oct 20, 2015 · Explanation: The mass of an electron is listed as being equal to. melectron = 9.10938356 ⋅ 10−31kg. The unified atomic mass unit, or u, is defined as the mass of one nucleon, that is a proton or a neutron. More specifically, one unified atomic mass unit is equal to 1 12th of the mass of a carbon-12 atom. A carbon-12 atom has six protons and ...
