With the completion of this experiment, the percent composition of the green salt, KxFe(C2O4)y.zH2O, has been completely determined experimentally. The simplest (empirical) formula (x, y, z) can be calculated from the % composition. Once the formula is known it is possible to calculate the percent yield obtained in the original synthesis reaction.
