- A student is given a sample of red cobalt sulfate hydrate. She weighed the sample in a dry covered crucible and obtained a mass of 25.050 g for the crucible, cover, and sample. Before adding the sample, the crucible and cover weighed 23.422 g. She then heated 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 let the crucible cool, and found it had a lower mass; the crucible, cover and contents then weighed 24.321 g. In the process the sample was converted to blue anhydrous COSO Show all calculations necessary to answer the following questions. 1628 g hydrate 1.
