WebJul 29, 2024 · As you learned, the mass number is the sum of the numbers of protons and neutrons present in the nucleus of an atom. The mass number is an integer that is approximately equal to the numerical value of the atomic mass. Although the mass number is unitless, it is assigned units called atomic mass units (amu). WebJul 17, 2024 · The relative formula mass (aka the formula weight) is the sum of the atomic weights (not average atomic masses) of the atoms in the formula of a compound. It, unlike the formula mass, is a dimensionless quantity. It does not have any unit. Both the quantities have the same numerical value, they only differ in the unit. black friday sale golf shoes https://mission-complete.org
