The mass of 12 protons is approximately equal to 12 atomic mass units.
Neutrons have a slightly higher atomic mass compared to protons. Neutrons weigh approximately 1.0087 atomic mass units, while protons weigh approximately 1.0073 atomic mass units.
Atomic weight/ mass = number of protons + number of neutrons
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
Number of protons = atomic number = 6 atomic units Number of protons + neutrons = mass number = 13 atomic units

Atomic weight/ mass = number of protons + number of neutrons
The atomic number is the number of a chemical element in the periodic table of Mendeleev; the atomic number is equal to the number of protons and electrons. The atomic mass is the mass of an atom expressed in relative atomic mass units.
The atomic mass (or weight) of silver is 107.8682 amu (atomic mass units)
Number of protons = atomic number = 6 atomic units Number of protons + neutrons = mass number = 13 atomic units
The formula mass of neon is equal to its atomic mass in atomic mass units (amu). This is because neon, like all elements, exists as individual atoms and its formula weight is the same as its atomic weight.
This is sum of the atomic weights of elements contained in the formula.
The approximate mass of an oxygen atom in atomic mass units is 16. Oxygen has an atomic number of 8, which means that its atomic mass is approximately 16 atomic mass units.
