2 moles of Ag is how many
atoms?

1.2 x 10²⁴ atoms

Explanation:

Given:

      Number of moles of Ag  = 2moles

 Unknown is the number of atoms it contains:

Solution:

A mole of any substance is known to be made up of 6.02 x 10²³ atoms

  Now;

          2 moles of an atom will contain:

                         2 x 6.02 x 10²³  = 1.2 x 10²⁴ atoms
