Understanding the Concepts
* Mole (mol): A unit of measurement used for the amount of a substance. One mole contains Avogadro's number of particles (atoms, molecules, etc.).
* Avogadro's Number: 6.022 x 10²³ particles per mole.
Calculation
1. Hydrogen is diatomic: Hydrogen gas exists as H₂, meaning each molecule contains two hydrogen atoms.
2. Atoms per mole: One mole of hydrogen (H₂) contains 2 * Avogadro's number of hydrogen atoms.
3. Total atoms:
* 2.4 moles H₂ * (2 atoms H / 1 molecule H₂) * (6.022 x 10²³ molecules H₂ / 1 mole H₂)
* = 2.89 x 10²⁴ hydrogen atoms
Therefore, there are approximately 2.89 x 10²⁴ hydrogen atoms in 2.4 moles of hydrogen.
