Number of moles of Zn = 0.48 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 atom
0.48 mol × 6.022 × 10²³ atom / 1mol
2.89× 10²³ atom
