Web21 de abr. de 2016 · Explanation: Atomic mass unit is equal to one twelfth of the mass of an atom of carbon-12 isotope. Atomic mass of an element is the number of times an atom of that element is heavier than an atom of carbon taken as 12. Mass number is the sum of the number of protons and the number of neutrons. It is always a whole number. WebStep 2: Mass of one atom of carbon - 12: Mass of one mole of carbon - 12 = 12 g Mass of 6. 022 × 10 23 atoms of carbon - 12 = 12 g So, the mass of 1 atom of carbon - 12 = 1 …
