Atomic mass of potassium

It provides atomic mass, mass excess, nuclear binding energy, nucleon separation energies, Q-values, and nucleon residual interaction parameters for atomic nuclei of the isotope K-54 (Potassium, atomic number Z = 19, mass number A = 54). mole = molecular weight / mass (mulitply both sides by mass) mole * mass = molecular weight (divide both sides by mole) mass = molecular weight / mole. As 1.626×10 23 molecules of NaOH is also equal to 0.27 moles, and we know that the molecular weight of NaOH is 40, we can use these numbers to get: mass = 40 / 0.27 = 10.8 g

The atomic mass (ma) is the mass of a single atom, when the atom is at rest at its lowest energy level (or "ground state"). Given that a chemical element may exist as various isotopes, possessing different numbers of neutrons in their atomic nuclei, atomic mass is calculated for each isotope separately.
