Detailed explanation-1: -Mass of proton = 1.007825 a.m.u. and Mass of neutron = 1.008665 a.m.u.
Detailed explanation-2: -Consequently, the nucleus accounts for almost the entire mass of the atom of any element, which means that a single proton or neutron has an approximate mass of 1 AMU. Atomic mass unit is one-twelfth the mass of an atom of carbon-12 (12C), the most common carbon isotope.
Detailed explanation-3: -A neutron is a subatomic particle that has a mass. 675 × 10-24 g, of approximately 1 amu, or nearly equal to the mass of a proton or hydrogen atom, and carries no electrical charge.
Detailed explanation-4: -Mass Number Protons and neutrons both weigh about one atomic mass unit (amu). Isotopes of the same element will have the same atomic number but different mass numbers.
