Expert Solution

Step 1

Mole concept:

The number of molecules or atoms present in the one mole of the substance is equal to the Avogadro number. The value of the Avogadro number is 6.022x10²³. The mass of one mole of a substance is known as the molar mass.

The mass of Ag is = 34.8 g

We know that the molar mass of Ag is = 107.8682 g/mol
