**Question (b):** The number of moles of potassium that contains \(8.93 \times 10^{25}\) atoms. \[\Box \times 10^{\Box} \text{ mol}\] **Explanation:** This question involves calculating the number of moles of potassium based on a given number of atoms. The calculation is based on Avogadro's number, which is \(6.022 \times 10^{23}\) atoms/mol. To find the number of moles, you use the formula: \[ \text{Number of moles} = \frac{\text{Number of atoms}}{\text{Avogadro's number}} \] Substitute the given number of atoms into the formula: \[ \text{Number of moles} = \frac{8.93 \times 10^{25}}{6.022 \times 10^{23}} \] Calculate the value to find the number of moles of potassium.
