balance the equation. from the 4 g o ferrous ammonium sulfate, how much of that 4g is IRON?
so the blanced equation give you the mole relations:
how many moles of ferrous ammonum sulfate did you start with. From that, how many moles of the iron complex?
now, multiply that by the percent of iron in the original complex.
In this experiment 4.0g of ferrous ammonium sulfate is used. Assuming everything else is added in excess; calculate the theoretical yield of the iron complex. Work through the entire reaction sequence; do not simply assume the number of moles of limiting reaction equals the number of moles of your final product.
