    Answer:

    6.33×10¯²² g

    Explanation:

    From the question given above, the following data were obtained:

    Number of atoms = 6 atoms

    Mass of copper (Cu) =?

    From Avogadro’s hypothesis, we understood that:

    6.02×10²³ atoms = 1 mole of Cu

    But 1 mole of Cu = 63.5 g

    Thus,

    6.02×10²³ atoms = 63.5 g of Cu

    Finally, we shall determine the mass of 6 atoms of copper. This can be obtained as illustrated below:

    6.02×10²³ atoms = 63.5 g of Cu

    Therefore,

    6 atoms = (6 × 63.5) / 6.02×10²³

    6 atoms = 6.33×10¯²² g of Cu

    Therefore, the mass of 6 atoms of copper is 6.33×10¯²² g.
