Answer:
8749.73× 10²³ atoms of He
Explanation:
Given data:
Number of atoms of neon = ?
Number of moles of neon = 1452.96 mol
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
1452.96 mol × 6.022 × 10²³ atoms of He/ 1 mol
8749.73× 10²³ atoms of He
