Understanding Moles and Atoms
In chemistry, a mole is a fundamental unit that measures the amount of substance. One mole of any substance contains a specific number of particles, which can be atoms, molecules, or ions.
Avogadro's Number
- The number of atoms in one mole is known as Avogadro's number.
- This value is approximately 6.022 × 10^23 particles per mole.
Why 6.022 × 10^23?
- Avogadro's number was established to provide a bridge between the macroscopic scale of substances we can measure and the microscopic scale of atoms and molecules.
- It allows scientists to count particles in a given sample, making it easier to relate mass and chemical reactions.
Application in the Question
- In the given scenario, both Rahul and Sohan have taken 5 moles of carbon and sodium, respectively.
- Regardless of the type of atom, the number of atoms per mole remains constant at 6.022 × 10^23.
Conclusion
- Therefore, the correct answer regarding the number of atoms in one mole is option 'A': 6.022 × 10^23 atoms.
- This fundamental principle is crucial for understanding stoichiometry and chemical reactions in Class 9 chemistry and beyond.
