We can start the problem by setting up a balanced chemical equation for the reaction between iron and sulfur:
Fe + S -> FeS
From the equation, we can see that the ratio of iron to iron sulfide is 1:1, meaning that the mass of iron sulfide produced is equal to the mass of iron that reacted. Therefore, the mass of sulfur that reacted can be found by subtracting the mass of iron from the total mass of iron sulfide:
mass of sulfur = 8.79 g - 5.58 g = 3.21 g

If 558 G of Iron Reacts with Sulfur to Produce 8
