Answer:
45.77 × 10²³ atoms
Explanation:
Given data:
Number of moles of iron = 7.6 mol
Number of atoms = ?
Solution:
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
7.6 mol × 6.022 × 10²³ atoms / 1 mol
45.77 × 10²³ atoms
