Understanding the Concept
* Mole (mol): A unit of measurement that represents a specific number of particles (atoms, molecules, ions, etc.).
* Avogadro's Number: The number of particles in one mole of any substance, which is approximately 6.022 x 10²³ particles/mol.
Calculation
1. Use Avogadro's Number: Since 1 mole of sodium contains 6.022 x 10²³ sodium atoms, we can use this as a conversion factor.
2. Multiply by the Number of Moles:
(4.8 mol Na) x (6.022 x 10²³ atoms Na / 1 mol Na) = 2.89 x 10²⁴ atoms Na
Answer: There are approximately 2.89 x 10²⁴ atoms present in 4.8 mol of sodium.
