Answer:
1) Measure initial masses of the crucible and cover with and without the hydrate.
2) Use a Bunsen burner to heat and dry the hydrate, repeating until the mass no longer decreases.
3) Measure the final masses of the crucible, cover, and anhydrous salt.
4) Compute differences in masses to find the reactants and products.
5) Use stoichiometry to convert these masses to moles.
6) Use the numbers of moles to compute the mole ratio.
7) Use the mole ratio to write the hydrate’s formula.
Explanation:
A hydrate is any substance that contains water of crystallization. The water of crystallization constitutes part of the mass of the substance. When heated to constant mass, the substance looses its water of crystallization and becomes anhydrous.
The mass of the anhydrous substance is now obtained by weighing again and subtracted from that of the hydrated substance. The masses are converted to moles using stoichiometry and the moles are then used to obtain the formula of the hydrate.
