Answer:

1.28 x 10²³ silver atoms.

Explanation:

  • It is known that 1.0 mole of atoms or molecules contains Avogadro's no. of atoms or molecules (6.022 x 10²³).

Using cross multiplication:

1.0 mole of silver → 6.022 x 10²³ silver atoms.

0.2124 mole of silver → ??? silver atoms.

∴ The no. of atoms of silver that are in 0.2124 moles of silver = (0.2124 mole)(6.022 x 10²³) / (1.0 mole) = 1.28 x 10²³ silver atoms.
