Answer:
10 gram of Sodium consists of 2.58 * 10^23 atoms.
Explanation:
- As we know 1 mole of an element consists of 6.023* 10^23 atoms. We calculate how many moles of sodium are in 10 g.
- Atomic Weight of Sodium is 23g.
- 1 mole of Sodium is equal to atomic weight of Sodium i.e. 23g.
- 10g of Sodium is equal to 1/23*10 moles which is equal to 0.43 moles of Sodium.
- 0.43 moles of Sodium consists of 6.023*10^23 * 0.43 atoms of Sodium which equals
Therefore, 10 gram of Sodium consists of 2.58 * 10^23 atoms.
