Here's how to calculate the number of atoms in 6 moles of Aluminum (Al):

Understanding the Concepts

* Mole: A mole is a unit of measurement that represents a specific number of particles (atoms, molecules, etc.). One mole contains 6.022 x 10²³ particles (Avogadro's number).

* Avogadro's Number: This constant (6.022 x 10²³) is the number of particles (atoms, molecules, etc.) in one mole of a substance.

Calculation

1. Start with the number of moles: You have 6 moles of Al.

2. Multiply by Avogadro's number: This will convert moles to the number of atoms:

6 moles Al * (6.022 x 10²³ atoms Al/mole Al) = 3.613 x 10²⁴ atoms Al

Answer: There are approximately 3.613 x 10²⁴ atoms in 6 moles of aluminum.
