one practical application of oxalic acid (H2C2O4) is as a rust remover. Rust is primarily composed of Fe2O3, which reacts with oxalic acid according to the unbalanced equation shown below.

Fe2O3 (s) + H2C2O3 (aq)  --> Fe(C22O4)3-3 (aq) + H2O (l) + H+ (aq)

Calculate the number of milligrams of Fe2O3 that can be removed using 500.0 mL of 0.1068 M H2C2O4.
