    Mass = 785.9 g

    Explanation:

    Given dа ta:

    Atoms of gold = 2.4 * 10²⁴ atoms

    Mass of gold = ?

    Solution:

    First of all we will convert the number of atoms into moles.

    2.4 * 10²⁴ atoms * 1 mol / 6.02 * 10²³ atoms

    number of moles = 3.99 mol

    Now we will determine the mass of gold.

    Mass = number of moles * molar mass

    Mass = 3.99 mol * 196.97 g/mol

    Mass = 785.9 g
