Pouring sulfuric acid over a pile of iron shaving leaves you with a pile of wet iron mixed in with product, which you probably have to dissolve anyway to get all your product. That's just a guess by the way.

To be clearer, the task was to dissolve 1g of iron in diluted sulfuric acid (concentrated wouldn't work for sulfate production) and it was specifficaly written to add as much acid so after the reaction takes place the solution of sulfate would still have acid (3% of total mass) in it.
