I am doing reox titration and not sure
how to do calculation of iron in tablets. Basically I find the concentration of potassium
permanganate solution using mol/vol. I know the volume but don't know the moles. Is it suppose to be written in the bottle? If so I forgot to write it down.

Once finding the concentration of potassium permanganate, we balance the redox equation of iron against KMnO4 and use the mol ratio. Then after finding how much moles of iron is present, sub into Mass=moles*molar mass. Is the iron solution formula Fe2O3?

Please help me as it is due tomorrow. Thank you very m
