Formula of a Hydrate
This lab was very fun! I enjoyed it a ton. In the lab, you find the CuSO4 * nH2O. To do this, you take the mass of the unknown sample, then heat it to drive away water molecules. After that, you determine the amount of water driven off by subtracting the CuSO4 anhydrous solution from CuSO4 * nH2O. The color change that occurs when heating the substance is quite cool to watch. It goes from a blueish crystal to a white powder.
A good website to help with Molar Mass!: https://www.boundless.com/chemistry/textbooks/boundless-chemistry-textbook/mass-relationships-and-chemical-equations-3/molar-mass-41/molar-mass-of-compounds-223-7524/
I liked the fact that you could see the change as it happened, and could clearly see the color change.
