The atomic mass unit (u) is defined as a mass equivalent to 1 / 12 of the mass of one atom of carbon-12. 1 u = 1.66 × 10 -27 kg. WebAnswer. Number of neutrons = Mass number − Atomic number. a. Number of neutrons = 125 − 53 = 72. b. Number of neutrons = 131 − 53 = 78. 4. Chlorine naturally exists in two isotopic forms: Cl35 17, Cl37 17.
