If an element has three isotopes with known masses, what other information is needed to find the average atomic mass of the element

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.

How can you use chemical equations to predict the products of the reaction you can carry out?
