Answer:
7.10 moles of iron
Explanation:
Given data:
Number of moles of iron = ?
Number of atoms of iron = 4.82×10²⁴
Solution:
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
4.82×10²⁴ atoms × 1 mol / 6.022 × 10²³ atoms
0.710×10¹
7.10 moles of iron
