3) A "free" neutron (that is, one outside of a nucleus) is unstable and decays into a proton, an electron, and an antineutrino. In this decay reaction, the sum of the kinetic energies of the proton, electron, and antineutrino has been measured to be 1.25 × 10¬13 J. The mass of the proton is 1.6726 × 10-27 kg, the mass of the electron is 9 × 10¬31 kg, and the mass of the antineutrino is much smaller than the electron mass (and can be ignored). Calculate the mass of the neutron from this information. Report at least 5 significant figures in your final answer.
