Answer:
2 moles
Explanation:
Given data:
Number of moles of Al = ?
Number of particles of Al = 1.204 × 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.
For example,
one mole of Al = 6.022 × 10²³ particles
1.204 × 10²⁴particles× 1 mol /6.022 × 10²³ particles
0.2 × 10¹ mole
2 moles
