Avogadro number:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance. The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ atoms
4.81 × 10²⁴ atom × 1 mol / 6.022 × 10²³ atoms
0.799 × 10¹ mol
7.99 moles
