Understanding the Concepts
* Mole (mol): A unit of measurement representing a specific amount of substance. One mole contains Avogadro's number of particles (atoms, molecules, etc.).
* Avogadro's Number: Approximately 6.022 x 10^23 particles per mole.
Calculation
1. Use Avogadro's Number: Since 1 mole of any substance contains Avogadro's number of particles, 2.2 moles of plutonium will contain 2.2 times that number of atoms.
2. Multiply:
* Number of atoms = (2.2 moles) * (6.022 x 10^23 atoms/mole)
* Number of atoms ≈ 1.32 x 10^24 atoms
Answer: There are approximately 1.32 x 10^24 plutonium atoms in 2.2 moles of plutonium.
