molar mass of Al =26.98g so 1.26g = 1.26/26.98=0.0467 mole of Al

2Al+3H2SO4->Al2(SO4)3+3H2 (2atoms of Al react with 3 molecules of H2SO4)

so you need 0.0467*3/2 moles of H2SO4 =0.07 moles of H2SO4

1L of 0.0124M H2SO4 contains 0.0124moles /L

volume needed 0.07/0.0124=5.649L or 5.649*1000=5649 mL of 0.0124M H2SO4
