How can I found mass with pourcentage yeid

Question

If 52.0 g of SO2 completely react and the percent yeild is 57.0%, how many grams of sulfurous acid, H2SO3(aq) are produced

Answer 1

If you know how to solve this normally: g SO₂ to moles SO₂ to moles of sulfurous acid to grams of sulfurous acid, just multiply by 0.57 at the end. If you go from product to reactant, you must divide by the yield at the end.
