0.625 moles of ge X 6.02x10^23 atoms/ 1 mol of ge equal to 3.76x10^23 atoms of ge, just times with Avogadro.

Answer:

3.76 × 10²³ atoms

Step-by-step explanation:

1 mole = 6.022 × 10²³ atoms (Avogadro's number)

Therefore, 0.625 moles of Ge will have:

Multiply the given moles by number of atoms per mole.

= 0.625 moles ×6.022 × 10²³ atoms/mol

= 3.76 × 10²³ atoms
