15.1  × 10²³ atoms

Explanation:

Given data:

Number of moles of Zn = 2.50 mol

Number of atoms = ?

Solution:

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,

18 g of water = 1 mole = 6.022 × 10²³ molecules of water

1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen

For 2.50 mole of Zn:

one mole of zinc = 6.022 × 10²³ atoms

2.50 × 6.022 × 10²³ atoms

15.1  × 10²³ atoms
