- 3/03/2012 · In my chemistry class, we did an experiment reacting iron with copper (II) sulfate. I found the experimental mole ratio of 1 mole Fe : 1 mole Cu. I know the equation is ((calculated experimental mole ratio - known mole ratio) / known mole ratio) x 100, but I have no idea how to use it. Can anyone help me find the percent error?
