2018, 3 (g) In a separate experiment, the student is given a sample of powdered Fe(s) that contains an inert
impurity. The student uses a procedure to oxidize the Fe(s) in the sample to Fe2O3(s). The student
collects the following data during the experiment.
Mass of Fe(s) with inert impurity
6.724 g
Mass of Fe2O3(s) produced
7.531 g
(g) Calculate the number of moles of Fe in the Fe2O3(s) produced.
