Answer:
2.86 × 10²⁴ atoms of gold
Explanation:
Given data:
Number of moles of gold = 4.75 mol
Number of atoms = ?
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.
One moles of substance = 6.022 × 10²³ atoms
4.75 moles of gold = 4.75 × 6.022 × 10²³ atoms of gold
28.61 × 10²³ atoms of gold
2.86 × 10²⁴ atoms of gold
