    The balanced equation for the reaction is as follows

    2Al + 3H₂SO₄ - - > Al₂ (SO₄) ₃ + 3H₂

    stoichiometry of Al to H₂SO₄ is 2:3

    number of Al moles reacted - 15.0 mol

    if 2 mol of Al react with 3 mol of H₂SO₄

    then 15.0 mol of Al reacts with - 3/2 x 15.0 mol = 22.5 mol

    22.5 mol of H₂SO₄ is required
