sorry, not sure I understand. the mass of persulfate should be weighed to only two decimal places then?
since, all of the answers rounded are the same, does that mean that the mass of ammonium persulfate should NOT be weighed accurately to two decimal places? instead, would need more decimal places to be more accurate?
