2. A student was asked to identify a sample of unknown hydrate. Student was provided with the following experimental data. 3.51 g sample of the hydrate when heated loses water completely and the mass of the residue was found to be 2.22 g. Student was provided with two reference compounds from which student needs to identify the unknown: Cu(NO3)2. 3H20 and Cu(NO3)2.6H2O. Answer the followings. a. Calculate percent water of hydration in the sample. (show your calculations) b. Identify the formula of the hydrate. 2.
