With the completion of the determinations of % potassium, %
iron, and % oxalate in the crystals, you may calculate the % water.
The percentage compositionof the crystals,
KxFe(C2O4)y ·
zH2O, has then been completely determined
experimentally. The simplest formula (x,y,z) can now be calculated
from the the percentage composition. Once the formula is know it is
then possible to calculate the percent yield of product that was
obtained in the preparation and purification of the crystals.
