I have idea what you're doing? What's the procedure. What's the starting material? You need to explain what's going on.
IF the sample is 100% ferrous ammonium sulfate hydrate then you will have 1.0714 of that material, of course.

Please check you numbers and repost everything. The value I'm getting for the grams of ferrous ammonium sulfate hexahydrate in a 1.0714 g sample and 70.5% Fe just doesn't seem possible.
