    First, we have to balance the equation:

    Al + H2SO4 → Al2 (SO4) 3 + H2

    we have the number of Al atoms not equal on both sides so we will put 2 Al instead of Al on the left side of the equation.

    2Al + H2SO4 → Al2 (SO4) 3 + H2

    now we have an unequal number of (SO4) group on both sides of the equation so we put 3H2SO4 instead of H2SO4

    2Al + 3H2SO4 → Al2 (SO4) 3 + H2

    now, we have to put 3H2 instead of H2 to make the H atoms equals on both sides.

    2Al + 3H2SO4 → Al2 (SO4) 3 + 3H2 this is the final balanced equation.

    ∴ the coefficient of H2SO4 is 3
