    8.03x10^23 atoms

    Explanation:

    From Avogadro's hypothesis, we understood that 1mole of any substance contains 6.02x10^23 atoms.

    This means that 1mole of potassium will also contain 6.02x10^23 atoms

    1 mole of potassium = 39g

    Now we can the above question as follows.

    If 1 mole (i. e 39g) of potassium contains 6.02x10^23 atoms, then 52g of potassium will contain

    = (52 x 6.02x10^23) / 39 = 8.03x10^23 atoms
