Question:

2 Al + Fe$$_2$$O$$_3$$ $$\longrightarrow$$ Al$$_2$$O$$_3$$ + 2 Fe

An operation requires at least 86.0 g of Fe to be produced. What is the minimum mass in grams of Fe$$_2$$O$$_3$$ necessary to produce the desired amount of products? How much Al$$_2$$O$$_3$$ is produced as a side product?

MM of Fe$$_2$$O$$_3$$ = 159.489 g/mol

MM of Al$$_2$$O$$_3$$ = 101.961 g/mol
