A mixture containing only Al2O3 (FM 101.96) and Fe2O3 (FM 159.69) weighs 2.019 g. When heated under a stream of H2, the Al2O3 is unchanged, but the Fe2O3is converted to metallic Fe plus H2O(g). If the residue weighs 1.774 g, what is the weight percent of Al2O3 in the original mixture?

Hi, I found the data in the attached table. The question I am struggling with is attached as well. Particuarly, the last sub-question, part C, which is about what happens to the hydrate formula if the copper sample (or crucible) is "wet" rather than "dry." I think that the hydrate formula would increase from 2 to 3, but could you confirm and explain what steps I would take to know this for sure? Thank you
You are performing an extraction and you begin with 0.70 g of crude starting material. At the conclusion of this exercise, you isolate 0.52 g of pure product. Calculate a percent recovery?
