Answer:

5.36 × 10²³ molecules

Explanation:

Given data:

Number of moles of silver = 0.89 mol

Number of molecules = ?

Solution:

Avogadro number:

The number 6.022 × 10²³ is called 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.  

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

Number of molecules of silver:

1 mole contain 6.022 × 10²³ molecules

0.89 mol  ×  6.022 × 10²³ molecules /1 mol

5.36 × 10²³ molecules
