- Solving applied mass percent problems Iron(II) sulfate forms several hydrates with the general formula FeSO, XH,O, where x is an integer. If the hydrate is heated, the water can be driven off, leaving pure FeSO, behind. Suppose a sample of a certain hydrate is heated until all the water is removed, and it's found that the mass of the sample decreases by 42.%. Which hydrate is it? That is what is?

A student is given a sample of a manganese(II) chloride hydrate. She weighs the sample in a dry, covered crucible and obtains a mass of 24.747 g for the crucible, cover, and sample. Earlier she had found that the crucible and cover weighed 23.599 g. She then heats the crucible to drive off the water of hydration, keeping the crucible at red heat for about 10 minutes with the cover slightly ajar. She then lets the crucible cool, and finds...
