Understand that 1 mole of any substance contains Avogadro's number of particles (atoms, molecules, ions, etc.).
Recall Avogadro's number, which is approximately \(6.022 \times 10^{23}\) particles per mole.
Since potassium (K) is an element, 1 mole of potassium contains exactly \(6.022 \times 10^{23}\) atoms of potassium.
Therefore, the number of potassium atoms in 1 mole of potassium is given directly by Avogadro's number.
No further calculations are needed; just recognize that 1 mole corresponds to \(6.022 \times 10^{23}\) atoms.
