B) 1.0 mol
C) 2.0 mol
D) 3.0 mol
E) 4.0 mol

219 grams of iron (iii) oxide reacts with excess carbon according to the reaction equation shown below. fe2o3 + c → fe + co2 after a scientist performs the chemical reaction they find the actual yield of iron to be 57.4 grams. calculate the percent yield of this chemical reaction.

Iam in desperate need of with this !
