Iron ii decomposes when heated strongly to give iron iii + sulfur oxide and sulfur traoxide
15,20grams of iron sulfate was heated and formed 4,8 grams of iron iii oxide . calculate the percentage yield for this reaction
write the balanced equation
see how many moles in 15,20 grams of iron sulfate
the equation will tell you how many moles of oxide to expect converted to grams
divide the 4,8 grams you got by how much you expected, times 100%
