Question

Potassium tris(oxalato)ferrate(III) trihydrate is prepared by precipitation from aqueous solution according to the following equation:
3 K2C2O4(aq) + FeCl3(aq) + 3 H2O(l) → K3Fe(C2O4)3 • 3H2O(s) + 3 KCl(aq)
A student mixes 10.00 g K2C2O4 (M = 166.2) and 5.00 g FeCl3 (M = 162.2) in 20.0 mL water and isolates 5.74 g K3Fe(C2O4)3 • 3H2O by filtration. What is the percent yield of this reaction?
