Willa weighs a clean, dry, empty crucible and finds it to have a mass of 95.83 g. After putting a spoonful of an unknown hydrate into it, she finds that the mass has increased slightly to 99.87 g. She heats the crucible and its contents, and finds that the mass has dropped to 97.22 g. Willa is told by her teacher that the molar mass of the anhydrous salt is 75.65 g.
