    The mass percent of sulfur is 28.12% (option 1)

    Explanation:

    Step 1: Data given

    Atomic mass of Al = 26.98 g/mol

    Atomic mass of S = 32.065 g/mol

    Atomic mass of O = 16.0 g/mol

    Step 2: Calculate the molar mass of Al2 (SO4) 3

    In 1 molecule Al2 (SO4) 3 we have 2 Aluminium atom, 3 Sulfur atoms and 12 oxygen atoms

    Molar mass of Al2 (SO4) 3 = 2*26.98 + 3*32.065 + 12*16.0

    Molar mass of Al2 (SO4) 3 = 342.155 g/mol

    Step 3: Calculate the mass percent of sulfur

    In 1 molecule Al2 (SO4) 3 we have 2 Aluminium atom, 3 Sulfur atoms and 12 oxygen atoms

    Mass % sulfur = (3*atomic mass of S / molar mass of Al2 (SO4) 3) * 100 %

    Mass % sulfur = (3*32.065 / 342.155) * 100%

    Mass % sulfur = 28.12 %

    The mass percent of sulfur is 28.12% (option 1)
