This is a simple question of Limiting Reagent.
Here is the balanced Equation : 2H₂S +SO₂ {tex}\rightarrow{/tex} 2H₂O + 3S
Thus if 2 moles of H₂S reacts with 1 mol of SO₂ then 3 moles of S will be formed
But in the given condition, SO₂ is only half mole (11.2 L of gas at STP represents half mole), thus it is limiting Reagent.
Thus if 1 mol of SO₂ gives 3 moles of sulfur, then 0.5 Moles of it will give 1.5 moles of sulfur.
