    15.05 * 10^23 atoms are present in 2.50moles of Al2 (SO4) 3

    Explanation:

    To solve this question, the Avogadro equation is used.

    Number of moles (n) = number of atoms (N) / Avogadro number.

    n = N / 6.02*10^23

    So therefore;

    2.50moles = N / 6.02 * 10^23

    N = 6.02 * 10^23 * 2.50

    N = 15.05 * 10^23 atoms.
