Understanding the Concepts
* Mole: A mole is a unit of measurement used in chemistry. It represents a specific number of particles, like atoms or molecules. One mole is equal to 6.022 x 10^23 particles (this number is known as Avogadro's number).
* Atoms: The smallest unit of an element that retains the chemical properties of that element.
Calculation
1. Avogadro's Number: We know 1 mole of any substance contains 6.022 x 10^23 particles.
2. Multiply by the number of moles: Since we have 2 moles of Helium, we multiply Avogadro's number by 2:
(6.022 x 10^23 atoms/mole) * 2 moles = 1.2044 x 10^24 atoms
Answer: There are approximately 1.2044 x 10^24 atoms in 2 moles of Helium.
