Question: 1 mole of silver has how many atoms?
Answer: 023 × 10^23 similarly 0.25 mole will contain 0.25 × 6.023 × 10^23. So 0.25 mole of silver also contain 0.25 × 6.023 × 10^23 atoms. The number of particles, in this case silver, in a mol of anything is 6.022×10^23 atoms or molecules or cars what it is does not matter as it is the same number for anything you choose.
