I did an experiment involving the gravimetric determination of Iron in Geritol.

At the end of the experiment I was left with a product, Fe2O3 that weighed 0.417 g

I'm not sure how to calculate the amount of Iron from here.

This is what I did.
I calculated the molar mass of Fe2O3 to be 159.6922 g.
Then I figured that Fe2O3 was 69.9433% Fe.

So I multiplied the weight of my product with the % to get 0.28096 g of Fe in my product.

Does this make any sense?

The manufacturer's analysis of Geritol says there should be 60 mg of elemental Iron per tablet.
(my sample contained two tablets)

Are my calculations wrong? Or did I mess up the experiment??

Please help ASAP!
