A cool crucible was weighed. The crucible weighed 24.8 g. The crucible was then removed from the scale and Hydrate 1 was added. The crucible was then weighed, containing the hydrate, which had a combined weight of 25 g. The hydrate alone weighed .2g. The hydrate was a royal blue solid with crystal features, it was rocky and clumpy, and was odorless. The crucible with the hydrate inside of it was then heated over a burner. Once taken off the burner, the crucible was set to cool and was then reweighed. The cooled hydrate had become an anhydrous since all the water had been evaporated from the substance. The crucible and the hydrate had a combined weight of 24.9g. The hydrate alone weighed .1g. The amount of water lost is a calculated .1g and the percent mass water in the hydrate was 50%.

The same procedure was conducted to Hydrate 2. The cooled crucible weighed 25.1 g. When the crucible was reweighed with hydrate 2, it had a combined weight of 26.3. The Hydrate weighed 1.2g. The hydrate consisted of white rocky solid with crystal features and was odorless. The crucible containing hydrate 2 was then burned and once the crucible was removed from the burner it was then cooled and reweighed. The cooled hydrate had become an anhydrous since all the water had been evaporated from the substance. The crucible and the hydrate had a combined weight of 25.8 g. The hydrate weighed .7 g. The amount of water lost is a calculated .5 g and the percent mass water in the hydrate was calculated to 58%.
