To determine the number of potassium atoms in 3.6 moles of potassium, we need to use Avogadro's number, which states that there are approximately 6.022 × 10^23 entities (atoms, molecules, etc.) in one mole of a substance.
Given that 1 mole of any substance contains Avogadro's number of entities, we can calculate the number of potassium atoms in 3.6 moles as follows:
Number of potassium atoms = (3.6 moles) × (Avogadro's number)
Number of potassium atoms = (3.6) × (6.022 × 10^23)
Calculating this, we get:
Number of potassium atoms ≈ 2.167 × 10^24
Therefore, there are approximately 2.167 × 10^24 potassium atoms in 3.6 moles of potassium.
