Iron can be extracted from iron ore according to the formula below. The percent yield of the reaction is 85.3%. Using excess carbon and 350 grams of Fe2O3, how many grams of iron can we expect to collect? Don't input units in answer boxes, numbers only. Use correct number of significant figures. 2 Fe2O3 + 3 C → 4 Fe + 3 CO2
