Calculate the theoretical yield of iron(III) oxide expected for this reaction if 0.50 mol of iron is reacted with excess oxygen
a_sh-v [17]
When you are dealing with mole calculations, whatever you do to one side of the equation you must also do to the other. .5Fe is 1/8th of 4Fe, so in order to determine what it will yield you must divide the given amount of Fe2O3 and divide THAT by 1/8th, leaving you with .25 mol of Fe2O3.
