Hence, the atomic mass is the sum of its protons and neutrons, which will be 12; therefore, 12u is the atomic mass of Carbon. Problem Sum to Calculate Atomic Mass Calculate the atomic mass of an element with an atomic number of 18 and a neutron number of 20. Solution: The number of...
How to calculate atomic mass? To find a reasonable approximation of the atomic mass of an atom in atomic mass units, we can simply add the number of protons and neutrons. So the atomic mass formula is: atomic mass (u) ≈ number of protons + number of neutrons Or A=Z+NA=Z+N where...
