    The number of hydrogen atoms that are in 4.40 mol of ammonium sulfide is 2.12 x10^25 atoms

    Explanation:

    calculation

    find the number of moles of Hydrogen in ammonium sulfide (NH4) 2S

    that is 4.40 x number of hydrogen atoms in (NH4) 2S (4x2 = 8 atoms)

    moles is therefore = 4.40 x8 = 35.2 moles

    by use of Avogadro's law constant

    that is 1mole = 6.02 x10^23 atoms

    35.2 moles=?

    by cross multiplication

    {35.2 moles x 6.02 x10^23} / 1 mole = 2.12 x10^25 atoms
