1. Understanding the Formula:
* CH4 represents one molecule of methane.
* It contains:
* 1 carbon atom (C)
* 4 hydrogen atoms (H)
2. Avogadro's Number:
* One mole of any substance contains 6.022 x 10^23 particles (atoms, molecules, etc.). This is called Avogadro's number.
3. Calculation:
* Atoms per molecule: 1 CH4 molecule has 1 + 4 = 5 atoms.
* Atoms per mole: Since one mole contains 6.022 x 10^23 molecules, one mole of CH4 contains 5 atoms/molecule * 6.022 x 10^23 molecules/mole = 3.011 x 10^24 atoms
Therefore, one mole of CH4 contains 3.011 x 10^24 atoms.
