Hi, I’m currently doing the calculations for the redox titration with iron tablets and KMnO4 and H2SO4. I have calculated the percentage mass of iron in each tablet but I’m unsure on how to calculate the amount of Iron sulfate in one tablet from this? :frown:

You should know the volume of acid used, and therefore the moles of acid that reacted. If you do the equation for the reaction, you should be able to work out the ratio of moles. Could you post the full question/method?
